Brain Cancer Treatment

 

Brain cancer can interfere with normal brain functions such as speech, movement, thoughts, feelings, memory, vision, and hearing. It is a disease of the brain in which abnormal, cancerous cells grow in the brain tissues. Typically, brain cancer is a developed form of a brain tumour. Primary brain cancer or a brain tumour develops from cells within the brain.

However, all brain tumours are not brain cancer. But one thing to note is that even benign tumour can cause serious problems by increasing intracranial pressure or obstruct vascular structures or cerebrospinal fluid flow in the brain.

Different types of cells in the brain such as gliomas, meningiomas, pituitary adenomas, vestibular schwannomas, and primitive neuroectodermal (medulloblastomas) can become cancerous. Gliomas have several subtypes, which include astrocytomas, oligodendrogliomas, ependymomas, and choroid plexus papillomas.

Types of Brain Cancers

There are two types of brain cancer, including:

  • Primary brain cancers: Primary brain cancers result when cancer cells develop in the tissues of the brain itself. Primary brain cancer cells may travel short distances within the brain but generally would not travel outside of the brain itself.
  • Secondary brain cancers: Secondary brain cancer is called metastatic brain cancer. It occurs when cancer develops elsewhere in the body and spreads to the brain. Primary cancer tissues can spread via direct extension, or through the lymphatic system or through the bloodstream.

Metastatic cancer in the brain is more common than primary brain cancer. They are usually named after the tissue or organ where cancer first develops. Metastatic lung or breast cancer in the brain is the most commonly found brain cancers.

Brain Cancer Causes

The exact brain cancer cause is still unknown. However, its occurrence has been linked to several risk factors, including the following:

  • Exposure to radiation
  • HIV infection
  • Inherited abnormality
  • Smoking
  • Exposure to environmental toxins
  • Exposure to chemical toxins, especially those used in rubber industry and oil refinery

Brain Cancer Symptoms

Some types of brain cancers such as meningeal and pituitary gland may produce few or no symptoms. Some of the brain cancer symptoms typically experienced by patients include:

  • Difficulty walking, seizures, dizziness and vertigo
  • Extreme fatigue and muscle weakness
  • Severe headaches and blurry vision
  • Sleepiness, nausea, and vomiting
  • Reduction in mental alertness, capacity or memory
  • Difficulty in speaking, impaired voice or inability to speak
  • Personality changes and hallucination
  • Weakness on one side of the body and coordination problems
  • Reduced touch sensation
Breast Cancer Treatment

The recent advances made in breast cancer treatment have revolutionized the way how women from this rare disorder are diagnosed and suggested a personalized treatment plan. These advances have made it easier for the doctors to arrive at a treatment plan, which is most suitable for the patient as per their individual characteristics and needs.

Different breast cancer treatment options help destruct complex mixture of cancer cells, which are otherwise difficult to treat using conventional breast cancer treatment. The treatment is started by the doctors handling the case as soon as the breast cancer diagnosis is confirmed.

Before the article delves into the different breast cancer treatment options, lets first take a look at how breast cancer develops and what are its symptoms and diagnosis methods.

Breast cancer: What do the statistics say?

Breast cancer primarily affects females aged above 40. However, that does not mean that it does not affect women aged below 40. Breast cancer can also affect males, although rarely.

Breast cancer starts in the cells of either one or both the breasts. It accounts for more than 16 percent of female cancer and contributes to 18.2 percent of all deaths that take place around the world because of cancer.

In the US alone, breast cancer affects more than 232,000 females and 2,200 males each year. It leads to death of more than 39,000 breast cancer patients in a year.

Breast Cancer Symptoms

The symptoms of breast cancer can be easily identified at home through breast self-examination. You should consult your physician on how to conduct this exam at home.

The most common breast cancer symptoms include:

  • Change in the size or shape of the breast
  • Lump in the breast
  • Swelling in armpit
  • Change in colour and shape of the nipples
  • Rash, redness or pitting on the breast skink
  • Pain in the breast or armpits
  • Abnormal discharge from the nipples

In case of more aggressive breast cancer called inflammatory breast cancer, severe redness and itching may be present.

The patients are advised to contact their physician as soon as they notice any of the symptoms of breast cancer. The physician is the best person to diagnose whether it is normal or inflammatory best cancer, and accordingly, suggest treatment for breast cancer.

Breast Cancer Causes

The exact reason that causes breast cancer is unclear, despite the fact that every eighth woman suffers from it. However, there are several factors that have been associated with the development of breast cancer. Some of the breast cancer risk factors include:

  • Prolonged use of birth control pills
  • Obesity
  • Use of hormone replacement therapy
  • High breast density
  • Alcohol addiction
  • No history of pregnancy
  • Pregnancy after 35
  • Exposure to radiation

The risk of breast cancer naturally increases as women age. The risk is also higher in women who have a family history of breast or ovarian cancer, possess BRCA1 and BRCA2 genes or who have had their periods before the age of 12.

Cervical Cancer Treatment

Cervical cancer is an abnormal growth of cancer cells that starts in the cervix. The cervix is the narrow part of the lower uterus. It is the entrance of the uterus, often referred to as the neck of the womb. Cervical cancer is the fourth most common type of cancer in women around the world. It is the fourth leading cause of death caused by cancer in women. However, the important thing to note is that cervical cancer is also one of the most preventable types of cancer and early diagnosis of the disease can improve the mortality rate amongst patients.

A dramatic reduction in cervical cancer occurrence is primarily due to the widespread use of advanced screening tests such as pap tests to detect cervical abnormalities and allow for early treatment.

Where does cervical cancer take place?

Under normal circumstances, the ectocervix is covered with flat, thin cells called squamous cells and the endocervix is made up of another kind of cells called columnar cells. The area where these cells meet is called the transformation (T) zone. The T zone is the most likely location for cervical cancer cells to develop.

Cervical Cancer Causes

A majority of cervical cancer cases occur because of a virus called human papillomavirus (HPV). HPV is a sexually transmitted virus. It can transfer through a sexual contact with an infected male partner.

There are many types of the HPV virus and not all types of HPV cause cervical cancer. Some of the HPV may cause genital warts. Some other cervical cancer risk factors include smoking, weak immune system, oral contraceptives, and multiple pregnancies.

Cervical Cancer Types

More than 90 percent of the cervical cancers are squamous cell carcinoma. The second most common type of cervical cancer is adenocarcinoma. Adenosquamous carcinomas or mixed carcinomas are some of the rare types of cervical cancer.

Cervical Cancer Symptoms

Usually, there are no early signs of cervical cancer, but several cervical cancer symptoms may appear as the tumor grows in size. Some of the common cervical cancer symptoms include the following:

  • Bleeding between periods
  • Bleeding during sexual intercourse
  • Bleeding after menopause
  • Smelly or blood-filled vaginal discharge
  • Pelvic pain, back pain, and swollen legs
  • Weight loss
  • Fatigue 
Colorectal Cancer ( Colon Cancer ) Treatment
  • Overconsumption of animal protein, saturated fats, and calories
  • Low dietary fibre intake
  • Overconsumption of alcohol
  • Excessive smoking
  • Family history of colorectal cancer
  • Obesity
  • Physical inactivity

Colorectal cancer is the second most common cancer in the world. It can metastasize and spread to other body parts. Colorectal cancer is dangerous and can be life-threatening. But death rate from colorectal cancer has dropped in the recent years, thanks to advance screening techniques and better colorectal treatment options.

What is colon cancer?

Colorectal cancer is also known as bowel cancer, colon cancer, or rectal cancer. Colorectal cancer begins as an abnormal growth of cells in the inner lining of the colon or rectum. This abnormal growth is called a polyp.

Some types of polyps can change into cancer over the course of several years. But it does not mean that all polyps have the tendency to become cancerous. The chance of changing a polyp into colorectal cancer depends on the type of polyp that grows. 

Colorectal cancer can affect men and women equally. However, studies have proven that men might develop it at a younger age.

What causes colon cancer?

There is no definite cause of colorectal cancer, but old age and certain lifestyle factors can increase colorectal cancer risk. Some of these colorectal cancer risk factors include the following:

Types of Colorectal Cancer

A majority of colorectal cancers are adenocarcinoma. If you have been diagnosed with colorectal cancer, there are 95 percent chances that it is an adenocarcinoma. But there are some other types of colorectal cancer such as carcinoid, gastrointestinal stromal, lymphomas, and sarcomas.

Colorectal Cancer Symptoms

There are no early signs of colorectal cancer, but once it grows, the patients may experience the following colon cancer symptoms:

  • Fatigue, weakness, and shortness of breath
  • Change in bowel habits, including diarrhoea or constipation
  • Blood in stool
  • Abdominal discomforts such as cramps, bolting or pain
  • Dramatic weight loss
Lung Cancer Treatment

Lung cancer is an uncontrolled growth of cells that start off in the lungs. Usually, lung cancer starts in the cells that line the air passages. Instead of developing into healthy lung tissue, the cells divide rapidly and form tumours.

Lung cancer can grow and spread beyond the lung to reach other parts of the body through metastasis. Lung cancers can begin in any part of the lung, but 90 percent of lung cancers begin in the epithelial cells, which are the cells lining the larger and smaller airways also known as bronchi and bronchioles.

This is the reason why lung cancers are sometimes called bronchogenic cancers or bronchogenic carcinomas. Lung cancer is the most common cancer in the world, among both men and women. It is the leading cause of cancer deaths worldwide.

Lung Cancer: Causes and Risk Factors

Long-term smoking is the main cause of lung cancer. After smoking, genetic factors and exposure to radon gas, asbestos, second-hand smoke or other forms of air pollution can also increase the risk of lung cancer.

Types of Lung Cancer

There are two major types of lung cancers, based on the appearance of lung cancer cells under the microscope:

  • Non-small cell lung cancer (NSCLC): It is an umbrella term for several types of lung cancers that behave in a similar way, such as squamous cell carcinoma, adenocarcinoma, and large cell carcinoma.
  • Small cell lung cancer (SCLC): This type of lung cancer occurs mostly in heavy smokers and it is less common than non-small cell lung cancer. 

Lung Cancer Stages

It is necessary to determine the stage of lung cancer by finding out how far cancer has spread, before initiating treatment of lung cancer.
The following are the four lung cancer stages of NSCLC:

  • Stage 1 lung cancer: Cancer is restricted to the lung
  • Stage 2 lung cancer: Cancer has spread to the nearby lymph nodes
  • Stage 3 lung cancer: (3a) Cancer is in the lung and the lymph nodes located on the same side  (3b) Cancer is in the lung and has spread to lymph nodes on the opposite side
  • Stage 4 lung cancer: Cancer has spread to both the lungs and other organs and surrounding tissues

The following are the two lung cancer stages of SCLC:

  • Limited stage: Cancer is present in just one lung and lymph nodes on the same side of cancer.
  • Extensive stage: Cancer has spread throughout the lung or both the lungs, to the lymph nodes on the opposite side, to the bone marrow, and to the distant organs.

After the determination of stage, treatment of lung cancer starts with choosing the best suitable option for the patient. However, there is usually no single treatment for lung cancer. So the patient often receives a combination of therapies and palliative care. 

Lung Cancer Symptoms

Lung cancer symptoms may vary, depending upon where and how widespread the tumour is. A person with lung cancer may have following lung cancer symptoms:

  • A persistent or chronic coughing
  • Pain in chest, shoulder or back
  • Difficulty in breathing and shortness of breath
  • Hoarseness or change of voice
  • Chronic bronchitis, pneumonia or respiratory infections
  • Blood in the sputum and cough


Stage 3 lung cancer symptoms include the following:

  • Wheezing
  • General pain in the chest or when breathing
  • Persistent cough with or without blood
  • Altered voice
  • Loss of appetite
  • Unplanned weight loss
  • Fever, headache, weakness, and bone pain
  • Difficulty swallowing
Mastectomy

Mastectomy refers to the partial or complete surgical removal of one or both the breasts. This surgery is most often indicated for breast cancer.

A lump in the breast or armpits is one of the earliest signs of breast cancer. It can cause a change in the shape, size, or color of the breast or nipple. Nipple tenderness, inward folding of the nipple, discharge from the nipple, and orange peel appearance of the skin of the breast are the other signs of breast cancer. Patients who observe any of the above-mentioned signs must see their physician immediately.

Who are advised to undergo breast cancer mastectomy?

Your physician may recommend you to undergo a partial or full mastectomy in the following conditions:

  • If you have a massive malignant tumor in the breast or invasive ductal carcinoma
  • If you have had a recurrent breast cancer after initial lumpectomy
  • If you are pregnant and have been diagnosed with breast cancer and radiation therapy is contraindicated
  • If you have a medical history of scleroderma and have been diagnosed with breast cancer
  • If you are diagnosed with breast cancer and have a lump in the armpits

Additionally, if you have a family history of breast cancer or deleterious mutation of BRCA 1 and BRCA 2 genes, you are advised preventive mastectomy.

Oral cancer Treatment

Oral cancer, commonly referred to as mouth cancer or throat cancer, is an uncontrollable growth of cells in the oral cavity. It refers to cancer that develops in any of the parts that make up the mouth. It can include cancer of the lips, tongue, cheeks, the floor of the mouth, pharynx (throat), hard and soft palate and either of the sinuses. Mouth and oropharyngeal cancer can be life-threatening, but it could be prevented if the cancer is diagnosed early enough.

What Causes Oral Cancer?

Oral cancer is a result of a mutation in the DNA of the cells in the mouth. There are certain identified risk factors for mouth cancer that predisposes a person to oral cancer.

Some of the oral cancer risk factors include:

  • Smoking: Smoking tobacco (cigarettes, cigars, and pipes) contains nitrosamines and other chemicals that are known to cause cancer. People who are exposed to passive smoking also experience a small increase in their risk of oral cancer.  
  • Chewing tobacco: Use of any type of tobacco is one of the main reasons behind oral cancer. Chewing tobacco is not a safe alternative to cigarettes. It is a popular habit in parts of Asia and in some immigrant groups in Europe, North America, and Australia. The harmful substances in tobacco and betel can cause oral cancer.
  • Alcohol consumption: Drinking excessive alcohol increases the risk of oral cancer. Using tobacco and alcohol both pose a much greater risk than using either of the substance alone.
  • Poor diet: Lack of vitamins and minerals, such as iron or folic acid in the diet, can lead to a breakdown in the oral mucosa and this can make people more prone to oral cancer. People should eat plenty of proteins, vitamins, and minerals to decrease the risk of oral cancer. Fresh fruits and vegetables contain a lot of antioxidants, vitamins and other substances that help prevent damage to body cells.
  • A family history of disease: There is a slightly higher risk of getting oral cancer in people who have a close relative who once had oral cancer.
  • Human Papilloma Virus (HPV): HPV can contribute to some types of cancers, but it does not mean that people get these cancers like an infection. HPV can be passed on to another individual during a sexual contact, but for a majority of people, the virus is harmless and does not cause any trouble. Only a very small percentage of people with HPV end up developing oral cancer.

Oral Cancer Symptoms

There are some typical signs of mouth cancer that a majority of patients experience. Make sure to visit your doctor or dentist in case you experience any of the following signs of mouth cancer:

  • Pain and discomfort in the mouth: Ongoing pain or discomfort from a long time in the mouth is the one of the most symptoms.
  • Ulcers and sore: Bleeding ulcer or sore, which is not healing for more than two weeks can be a symptom of oral cancer.
  • Unexplained bleeding: Unexplained bleeding in the mouth can be an alarming indication of oral cancer.
  • Numbness and lost sensation: Numbness, loss of feeling or tenderness in any area of the mouth, or neck can be a symptom.
  • White or red patches: Any abnormal looking patches in the mouth or throat could be a sign of cancer or precancerous changes. Although, a fungal infection called thrush can also be the reason for white or red patches.
  • Difficulty in swallowing: You may feel difficulty in chewing and swallowing and feel like your food is sticking in your throat. Feeling difficulty in speaking or moving the jaw and tongue can be one of the most important throat cancer symptoms.
  • Weight loss: Dramatic weight loss without any reason can also be a symptom.
Ovarian Cancer Treatment

Ovarian cancer refers to the abnormal growth of cells in the ovaries, which are an important part of the female reproductive system. Ovaries are two small glands, located on either side of the uterus. They help produce female sex hormones and store or release eggs. An ovarian tumor is it is the eighth most common type of cancer among women. It is the fifth most common cause of cancer deaths in women around the world. Ovarian cancer can be life-threatening if not diagnosed and treated on time, however, the chances of survival are great in the case of early diagnosis.

Ovarian cancer forms when normal ovarian cell growth fails, and there is an uncontrolled growth of cells. Most of the ovarian cancers arise from the lining cells (epithelium) of the ovary. The ovarian tumor can metastasize and spread to other organs of the body.

Ovarian Cancer: Causes

There is no identified and known cause of ovarian cancer. However, there are some risk factors associated with the disease. Family history (genetics) of ovarian cancer, older age, breast cancer, obesity, and endometriosis are some of the known ovarian cancer risk factors. Other than these, menstrual cycles play a major role in ovarian cancer. The high number of total lifetime ovulations, greater the risk of ovarian cancer.  That is, women who have had their periods before the age of 12 are at an increased risk of ovarian cancer.

The risk of ovarian cancer is also high in women suffering from familial melanoma, which is characterized by the presence of certain genes. These genes are inherited from parents and mostly occurs when two or more relatives suffer from the aggressive form of melanoma or skin cancer.

Signs of Ovarian Cancer

Typically, the symptoms of ovarian cancer are subtle during the early stage. However, the patients may experience signs of ovarian cancer once the cancer advances and starts to grow. The following are some of the ovarian cancer symptoms:

  • Pain in the pelvis or belly

  • Bloating

  • Frequent and urgent urination

  • Changes in bowel habits

  • Nausea and fatigue

  • Weight loss

  • Breathlessness

  • Loss of appetite

These signs of ovarian cancer can be confused with those of ovarian cyst. However, patients must know that ovarian cysts are far more common and primarily affects women during their childbearing age.
