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.

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

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.
