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
Microwave Endometrial Ablation

Endometrial ablation is an outpatient procedure that is used to remove the endometrial lining in the uterus of a woman suffering from unusually high menstrual bleeding. During the procedure, the endometrium is ablated or destroyed with the help of laser or microwave.

Endometrial ablation surgery is not recommended for women who wish to conceive in the future. This is because this procedure may permanently damage the layers of the uterus and the endometrium may no longer be suitable for the attachment of the developing fetus.

Uterine ablation is most commonly recommended for women who suffer from heavy menstrual bleeding and do not wish to undergo hysterectomy or the surgical removal of the uterus. This procedure is either conducted at the doctor’s office or at a hospital. It can be conducted under local or light anesthesia or general or spinal anesthesia.

Uterine ablation is not recommended for patients who have:

  • Uterine, cervical, or vaginal infection
  • Pelvic inflammatory disease (PID)
  • Endometrial, uterine, or cervical cancer
  • An intrauterine device (IUD)
  • Pregnancy
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.
