When breast cancer is diagnosed, the first step is to determine the type of cancer by examining the characteristics of the tumor. For this reason, to take a tissue sample or biopsy of breast tumor is removed surgically if the pathology is examined by a doctor. This information will help in determining which treatment options that is more appropriate for you.
Your cancer invasive (radiating) or non-invasive (not the spread) is?
If your breast cancer has spread anywhere your cancer your doctor will be invasive or noninvasive treatment that is more suitable for you, the risk of developing breast cancer in the same breast or the other helps to determine what is wrong.
- Noninvasive (in their place) breast cancer: Remaining in their place (spread) breast cancer cells remaining in the central region of the channel or around the breast tissue and are unable to spread to lopcuk. Ductal carcinoma in situ (in place), called non-invasive type of cancer pre-cancerous lesion is regarded as. This is released in the body when it is in DCIS means that can turn into invasive cancer.
Called lobular carcinoma in situ, non-invasive other types of cancer (BREAST cancer) because they are not defined as a pre eventually do not turn into invasive cancer. WOMEN can increase the risk of cancer in both breasts. - Invasive breast cancer: Invasive (infiltrating) breast cancer may spread to the outside of the membrane channel or lopcuk around, and to invade nearby tissues. Cancer cells are able to go to other parts of the body such as lymph nodes. Breast cancer and your I, ii, iii, IV. as such, the stages involved, means you have breast cancer.
Breast cancer can start where sections include :
- Milk pipes: Ductal carcinoma is the most common type of breast cancer. The pipe consists of covering this type of cancer in breast milk. Where is the milk produced lopcuk of these pipes has nipples.
- Lopcuk milk production are: Lobular carcinoma starts in the lobules of the breast where the milk is produced. Lobules are connected to the tube that carries milk on your nipples.
- Connective tissues: Although rare, breast cancer, muscles, fat and blood vessels is made up of connective tissue, which consists of the structure, which begin in May. Sarcoma-cancer that begins in the connective tissue (joint control) is called. Examples of tumors occurring in the breast and sarkoma filloides anjiyosarkom covers.
Cancer tissue are examined by pathologists ?
A sample of your breast cancer when it is examined under a microscope, the pathologist in these examples is seeking the following :
- Cancer cells have unique features: When viewed under a microscope, they appear to be different than invasive ductal carcinoma cells. Types of invasive ductal carcinoma tubular, mucinous, medullary and papillary contains a structure that can be viewed under a microscope. In the diagnosis of subtypes and provide clues to how it will react to your doctor about your treatment cells.
- The degree of the differences between cancer cells and normal cells: Normal cells, cancer cells of the cancer that determines the degree is different in the amount of. Breast cancer is rated with a ratio between 1 and 3, 3-grade cancers are considered the most aggressive and difference is a maximum.
The cancer cells with hormones relationship.
Some breast cancers are sensitive to female hormones estrogen and progesterone that occurs naturally in your body. Breast cancer cells outside the walls, there are special receptors which can capture hormones circulating in your body. Knowing your breast cancer sensitivity to hormones, cancer can be treated in the best way for you, or for measures to be taken to prevent the occurrence of cancer gives your doctor a better idea.
The hormonal status of breast cancer are mentioned below :
- Estrogen receptor (ER) positive: This type of breast cancer is sensitive to estrogen.
- Progesterone receptor (PR) positive: Projesteron are sensitive to this type of breast cancer.
- Hormone receptor (HR) negative: This type of cancer have hormone receptors, and hence will not affect the purpose of the Prevention of treatment with hormones in the body.
ER-positive or PR-positive breast cancers, the growth of hormone-blocking medications while slowed with HR-negative cancers are hormone-based treatments does not react to.
The importance of the genetic profile of breast cancer cells
Treatment options doctors have begun to understand how DNA changes in cancer cells that are used to determine specific. All the information about how the DNA of a cell can act (genes) gives. By analyzing the genes, doctors hope to find ways to destroy cancer cells by targeting specific aspects.
Your cancer cells reveals certain genes in laboratory tests. They include :
- Her-2 gene: EACH-2 many copies of the gene in the cancer cells with her-2 protein produces many growth booster called. EACH-2 to neutralize the protein drugs are available, these cancer cells and slow the growth of cancer cells and kills them.
- Other genes: Researchers are continuing studies to interpret the genetic profile of tumor cells. This information will spread and how aggressive the cancer, which doctors treatment can be applied to estimate the extent of a hope to be able to use.
Cancer-related genetic information using kanserlerii breast can be categorized in groups. According to the genetic profile of cancer treatment options that can help you categorize, which related to more appropriate. Breast cancer groups are listed below :
- Group 1 (luminal A): This group of ER-positive and PR-positive tumors that contain includes, but EACH-2 is negative. Luminal A breast cancers perceive benefit from hormone therapy and chemotherapy.
- Group 2 (luminal B): ER and PR positive tumors that contain this group includes negative and her-2 positive. Luminal B breast cancers chemotherapy and hormone therapy and her-2 targeted therapy appear to benefit from
- Group 3 (her-2 positive): This type of ER-negative and PR-negative tumors includes, however, her – 2 positive. Her – 2 breast cancer and her-2 targeted therapy to benefit from.
- Group 4 (basal-like): Triple-negative breast cancer called this type of ER negative, PR negaitf and her-2 negative tumors includes. Basal-like breast cancers perceive benefit from chemotherapy.
