KATHERINE 'MARIE' MARTIN
Breast Cancer Awareness Month
Every September, We at hiphoptv247.org will bring awareness to Breast Cancer in honor of Katherine 'Marie' Martin, a long time breast cancer survivor who has recently succumbed to the fatal disease.
Breast cancer is the most common cancer in women in the
If you're worried about developing breast cancer, or if you know someone who has been diagnosed with the disease, one way to deal with your concerns is to get as much information as possible. In this section you'll find important background information about what breast cancer is and how it develops.
Breast cancer is a malignant tumor that grows in one or both of the breasts. Breast cancer usually develops in the ducts or lobules, also known as the milk-producing areas of the breast.
Breast cancer is the second leading cause of cancer death in women (after lung cancer). Although African-American women have a slightly lower incidence of breast cancer after age 40 than Caucasian women, they have a slightly higher incidence rate of breast cancer before age 40. However, African-American women are more likely to die from breast cancer at every age. Breast cancer is much less common in males; by comparison, the disease is about 100 times more common among women. According to the American Cancer Society, an estimated 1,910 new cases of invasive breast cancer are expected to be diagnosed among men in the
Types of breast cancer
There are several different types of breast cancer that can be divided into two main categories - noninvasive cancers and invasive cancers. Noninvasive cancer may also be called "carcinoma in situ." Noninvasive breast cancers are confined to the ducts or lobules and they do not spread to surrounding tissues. The two types of noninvasive breast cancers are ductal carcinoma in situ (referred to as DCIS) and lobular carcinoma in situ (referred to as LCIS).
It is known that hormones in a woman's body, such as estrogen and progesterone, can play a role in the development of breast cancer. In breast cancer, estrogen causes a doubling of cancer cells every 36 hours. The growing tumor needs to increase its blood supply to provide food and oxygen. Progesterone seems to cause stromal cells (the woman's own cells to send out signals for more blood supply to feed the tumor. (Source: Dr. V.

- Non-invasive breast cancer. The majority of non-invasive breast cancers are DCIS. In DCIS, the cancer cells are found only in the milk duct of the breast. If DCIS is not treated, it may progress to invasive cancer.
In LCIS, the abnormal cells are found only in the lobules of the breast. Unlike DCIS, LCIS is not considered to be a cancer. It is more like a warning sign of increased risk of developing an invasive breast cancer in the same or opposite breast. While LCIS is a risk factor for invasive cancer, it doesn't actually develop into invasive breast cancer in many women. - Invasive breast cancer. Invasive or infiltrating breast cancers penetrate through normal breast tissue (such as the ducts and lobules) and invade surrounding areas. They are more serious than noninvasive cancers because they can spread to other parts of the body, such as the bones, liver, lungs, and brain.
There are several kinds of invasive breast cancers. The most common type is invasive ductal carcinoma, which appears in the ducts and accounts for about 80 percent of all breast cancer cases. There are differences in the various types of invasive breast cancer, but the treatment options are similar for all of them.
Not all breast cancers are alike
Not all breast cancers are alike - there are different stages of breast cancer based on the size of the tumor and whether the cancer has spread. For doctor and patient, knowing the stage of breast cancer is the most important factor in choosing among treatment options. Doctors use a physical exam, biopsy, and other tests to determine breast cancer stage.
Stages of Breast Cancer
The most common system used to describe the stages of breast cancer is the AJCC/TNM (American Joint Committee on Cancer/Tumor-Nodes-Metastases) system. This system takes into account the tumor size and spread, whether the cancer has spread to lymph nodes, and whether it has spread to distant organs (metastasis).
All of this information is then combined in a process called stage grouping. The stage is expressed as a Roman numeral. After stage 0 (carcinoma in situ), the other stages are I through IV (1-4). Some of the stages are further sub-divided using the letters A, B, and C. In general, the lower the number, the less the cancer has spread. A higher number, such as stage IV (4), means a more advanced cancer.
These are the stages of breast cancer:
Stage 0 - Stage 0 is carcinoma in situ, early stage cancer that is confined to the ducts or the lobules, depending on where it started. It has not gone into the tissues in the breast nor spread to other organs in the body.
- Ductal carcinoma in situ (DCIS): This is the most common type of noninvasive breast cancer, when abnormal cells are in the lining of a duct. DCIS is also called intraductal carcinoma. DCIS sometimes becomes invasive cancer if not treated.
- Lobular carcinoma in situ (LCIS): This condition begins in the milk-making glands but does not go through the wall of the lobules. LCIS seldom becomes invasive cancer; however, having LCIS in one breast increases the risk of cancer for both breasts.
Stage I - Stage I is an early stage of invasive breast cancer. In Stage I, cancer cells have not spread beyond the breast and the tumor is no more than 2 centimeters (three-quarters of an inch) across.
Stage II - Stage II is one of the following:
- The tumor in the breast is no more than 2 centimeters (three-quarters of an inch) across. The cancer has spread to the lymph nodes under the arm.
- The tumor is between 2 and 5 centimeters (three-quarters of an inch to 2 inches). The cancer may have spread to the lymph nodes under the arm.
- The tumor is larger than 5 centimeters (2 inches). The cancer has not spread to the lymph nodes under the arm.
Stage III - Stage III may be a large tumor, but the cancer has not spread beyond the breast and nearby lymph nodes. It is locally advanced cancer.
- Stage IIIA - Stage IIIA is one of the following:
- The tumor in the breast is smaller than 5 centimeters (2 inches). The cancer has spread to underarm lymph nodes that are attached to each other or to other structures.
- The tumor is more than 5 centimeters across. The cancer has spread to the underarm lymph nodes.
- Stage IIIB - Stage IIIB is one of the following:
- The tumor has grown into the chest wall or the skin of the breast.
- The cancer has spread to lymph nodes behind the breastbone.
- Inflammatory breast cancer is a rare type of Stage IIIB breast cancer. The breast looks red and swollen because cancer cells block the lymph vessels in the skin of the breast.
- Stage IIIC - Stage IIIC is a tumor of any size. It has spread in one of the following ways:
- The cancer has spread to the lymph nodes behind the breastbone and under the arm.
- The cancer has spread to the lymph nodes under or above the collarbone.
Stage IV - Stage IV is distant metastatic cancer. The cancer has spread to other parts of the body.
Recurrent cancer - Recurrent cancer is cancer that has come back (recurred) after a period of time when it could not be detected. It may recur locally in the breast or chest wall as another primary cancer, or it may recur in any other part of the body, such as the bone, liver, or lungs, which is generally referred to as metastatic cancer.
