Ovarian Cancer Survival Rate

Sunday, June 27, 2010 posted by 11:22 pm





For most sufferers and their families the main question they have is regarding ovarian cancer survival rates. Before we get into this let’s focus on what ovarian cancer is. The ovarian cancer is a disease that affects one or both ovaries, the organs on each side of the uterus. One of the ovaries releases an ovum when a woman ovulates. The ovaries also make hormones for reproduction. Unfortunately, approximately 75% of ovarian cancers are diagnosed at an advanced stage. If it is detected early and treated, the ovarian cancer survival rate is good. Patients increase the ovarian cancer survival rate if it has not spread outside the ovary and have a 90-95% chance of surviving five years or more after treatment.

The type of cancer is based on the cell type where it occurs. The most common is the epithelial cancer. Approximately 85 to 90% of all cancer cases arise from epithelial cancer that occurs in the cells on the surface of the ovary. Most women who develop this cancer are over 40 years of age. Approximately 5% of ovarian cancers are germ cell tumors. Stem cells are cells of the ovaries that become eggs. The cancer cells can also spread other than the abdominal cavity, to the surface of the lungs and chest cavity, resulting in a collection of fluid around the lungs known as a pleural effusion.

Who are at risk? About 3% of all new cancer cases diagnosed each year in women are ovarian cancers. Women of any age can develop ovarian cancer, but the risk increases with age. The most common type occurs more frequently in women between 50 and 75 years of age. Half of all ovarian cancer cases are diagnosed in women over 63 years of age. Ovarian cancer is much less common in women under 40 years of age. The following factors increase a woman’s risk of developing ovarian cancer:

  1. Family history of ovarian
  2. Personal history of breast cancer
  3. Late menopause
  4. Use of fertility
  5. Women who have never been pregnant, or who became pregnant for the first time at age 30 or older.
  6. Approximately 5-10% of all ovarian cancers occur in women who have certain genes (BRCA1 and BRCA2) inherited from their parents. There are blood tests to detect if a woman has one of these genes. Women who have one of these genes should consult a genetic specialist.

The prognosis says that the less a woman ovulates during her lifetime, the lower her risk of developing cancer of the ovary. Therefore, women who have had children have lower odds of developing ovarian cancer because they do not ovulate while pregnant or nursing. Women who use contraceptive pills do not ovulate and, therefore, have lower odds of developing ovarian cancer. Women who have undergone tubal sterilization seem to develop ovarian cancer less frequently, but the reason is unclear. After a doctor gives the diagnosis of ovarian cancer the treatment must start immediately. It’s important to understand that a woman can have some or all of the risk factors and yet never develop ovarian cancer and vice versa. All women should know the symptoms and inform their physicians, allowing the ovarian cancer survival rate to increase.

Treatments For Cervical Cancer

Sunday, June 27, 2010 posted by 11:15 pm





Before we look at the treatments for cervical cancer let’s look at how it spreads. The uterus is the hollow organ, inverted pear-shaped, where a foetus grows. Cervical cancer is a common type of cancer in women and is a disease in which cancerous cells are found in the tissues of the cervix. Cervical cancer begins to grow slowly. Before appearing cancer cells in the cervix, normal tissues of the cervix go through a process known as dysplasia, in which abnormal cells begins to appear. The Papanicolaou cytology usually finds these pre-malignant cells then they advance and spread more deeply into the cervix and surrounding areas. It’s important to attack the disease early before it reaches an invasive stage so the treatment for cervical cancer can start immediately. Remember that cancerous cells development advances rapidly.

Since there is usually no symptoms associated with cancer of the cervix diagnosis normally involves a series of tests ; Papanicolaou cytology (using a cotton swab, a brush or a small wooden spoon to gently scrape outside of the cervix to collect cells) and Biopsy (a sample of tissue from the cervix is removed to observe under a microscope).

The prognosis and choice of treatment depend on the stage of the cancer and the general state of health. The following stages are used in the classification of cervical cancer:

  1. Stage I – Cancer has not spread to the surroundings.

  2. Stage II – The cancer has spread to nearby areas.

  3. Stage III – Cancer has spread to the entire pelvic area. May have spread to the bottom of the vagina, or infiltrate the ureters.

  4. Stage IV – The cancer has spread to other parts of the body.

  5. Appellant – A recurrent disease, which means that the cancer has returned after having been treated. It can occur in the cervix itself or appear in another location.

There are three different type of treatments for all patients with cervical cancer; surgery, radiation therapy and chemotherapy. The physician according to the information collected will find out which is the best one for the patients. Recently, a vaccine called Gardasil has been developed. It has been shown to be effective against cervical cancer when given before a woman is exposed to HPV (HPV stands for Genital human papillomavirus which is the most common sexually transmitted virus in the United States. It is passed on through genital contact such as vaginal and anal sex). For this reason, Gardasil is a treatment option recommended and approved in girls and young women between the ages of 11-26 years.

For prevention, women should try to reduce risk factors as much as possible. Don’t smoke and put limits on the number of sexual partners. Unfortunately, condoms do not protect you from developing HPV, but will reduce the risk of developing cervical cancer. Many people are interested in preventing cervical cancer with vitamins or diets. Some may play a role in preventing cervical cancer, but no convincing data exists to suggest this. More studies need to be made before making dietary recommendations for the treatments for cervical cancer.

How Ovarian Cancer Metastasis Spreads

Sunday, June 27, 2010 posted by 10:59 pm





Ovarian cancer metastasis is a process that involves local tumor invasion followed by dissemination and then re-establishment at distant sites. It usually occurs through blood or lymphatic system, a network of conduits that carry a clear fluid. Approximately 98% of deaths from undetected cancers are due to ovarian cancer metastasis.

Cancers spread through the body by two mechanisms: invasion and metastasis. The invasion is the direct migration and penetration by cancer cells in nearby tissues. Metastasis is the ability of cancer cells to penetrate the blood and lymphatic vessels, circulate through the bloodstream and then grow into a new focus, ovarian metastasis in normal tissues elsewhere in the body. Ovarian cancer is the seventh most common cancer among women in the United States followed by the primary cancers, breast cancer and gastrointestinal cancer.

 

There are several different types of cancer that can arise in the ovary, including epithelial ovarian cancer that occurs in the cells on the surface of the ovary. Epithelial cancer is another term for ovarian cancer.

Studies make a special reference to Krukenberg tumor which refers to an ovarian cancer metastasis whose primary site arose in the gastrointestinal tract or breast. These tumors are often found in both ovaries. Patients with Krukenberg tumor often come to the attention of the doctor when they’re suffering from abdominal or pelvic pain, bloating, vaginal bleeding, a change in their menstrual habits or pain during intercourse. These symptoms are not specific, pointing to a number of other problems that the cancer and the diagnosis of the disease can only be made following computed tomography (CT), laparotomy and/or a biopsy of the ovary. A laparotomy is a surgical procedure involving an incision through the abdominal wall to gain access into the abdominal cavity. It is also known as coeliotomy. When treating a secondary metastatic tumor its origin, the primary tumor, should also be treated. On early staging ovarian cancer is associated with abdominal distension. Depending on the stage you can figure out the size of the tumor and how deeply it has penetrated.

The ovary is a common site of metastasis of certain primary carcinomas. Today science advances rapidly with new research that helps to prevent many diseases. Scientists have created a vaccine to prevent ovarian cancer metastasis. The results thus far show promise, both for their safety and for their effectiveness. Ovarian tumors are “stealthy murderers” because they are notoriously difficult to detect in their early stages. About 10% of ovarian tumors are of primary origin. Thus far, nobody has convincingly described the procedure normally followed to ovarian with metastases from gastric cancer. It is known that the lymphatic channels that drain the upper gastrointestinal tract end up joining the lumbar chain of lymph nodes. The only hope for improvement is the removal as soon as possible of the primary tumor. In terms of treatments adjuvant chemotherapy is effective to minimize the effects of ovarian cancer metastasis depending on the stage reached.
