Breast cancer is a situation in which cells in the breast grow out of control. There are specific types of breast cancer. The type of breast cancer depends on which cells within the breast develop into most cancers.
You can start in extraordinary elements of the breast. A breast is made up of 3 predominant components: lobules, ducts, and connective tissue. The lobules are the glands that produce milk. Ducts are tubes that carry milk to the nipple. Connective tissue (which includes fibrous and fatty tissue) surrounds and holds everything together. Most breast cancers start within the ducts or lobules.
Breast cancer can spread outside the breast through blood vessels and lymphatic vessels. When most breast cancers spread to other parts of the body, they are said to have metastasized.
More types of breast cancer
The most common types of breast cancer are:
• Invasive ductal carcinoma. Cancer cells grow outside the ducts into other parts of the breast tissue. Invading cells from most cancers can also spread or metastasize to other parts of the body.
• Invasive lobular carcinoma. Cancer cells spread from the lobules to breast tissues that may be nearby. These invasive cancer cells can also spread to other parts of the body.
There are many other less common types of breast cancer, such as Paget’s disease, inflammatory, mucinous, and external medullary breast cancer.
Ductal carcinoma in situ (DCIS) is a breast disorder that may cause most breast cancers. Cancer cells lie better within the lining of the ducts and no longer spread to other breast tissues.
Breast cancer risk factors
Studies have shown that your chance of breast cancer is due to a number of factors. The main elements that affect your opportunity include being a woman and getting older. Most breast cancers are seen in women age 50 and older.
Some women get breast cancer even without other risk factors that they recognize. Having a danger aspect doesn’t mean you’ll get the disease, and not all danger items have the same impact. Most women have some risk factors, but most women do not get breast cancer. If you have risk factors for breast cancer, talk to your doctor about methods that might lower your risk and about breast cancer screening.
Threat Items You Can’t Trade
• aging. The danger of most breast cancers increases with age; most breast cancers are identified after the age of 50 years.
• Genetic mutations. Inherited changes (mutations) in certain genes, including BRCA1 and BRCA2. Women who have inherited these genetic settings are at increased risk of breast and ovarian cancer.
• Reproductive records. Early menstrual periods before the age of 12 and the onset of menopause after the age of 55 show women hormones longer, which increases the risk of breast cancer
• Have dense breasts. Dense breasts have more connective tissue than fatty tissue, which can sometimes make it difficult to detect tumors on a mammogram. Women with dense breasts are more likely to get breast cancer.
• non-public history of most breast cancers or certain non-cancerous breast diseases. Women who have had more breast cancers are more likely to have breast cancer a second time. Some noncancerous breast diseases consisting of unusual hyperplasia or lobular carcinoma in situ are associated with an increased risk of breast cancer.
• family breast cancer registries. A woman’s risk of breast cancer is higher if she has a mother, sister, or daughter (first degree relative) or multiple contributing family members on both the mother’s and father’s sides of the family who have had breast cancer. Having a male relative with a primary degree and breast cancer also increases a woman’s risk.
• previous treatment using radiotherapy. Girls who received radiation therapy to the chest or breasts (such as for Hodgkin’s lymphoma) before age 30 have a higher risk of developing breast cancer later in life.
• Women who took the drug diethylstilbestrol (DES), which was given to some pregnant women in the United States between 1940 and 1971 to prevent miscarriage, are at higher risk. Women whose mothers took DES while pregnant are also at risk.
Threat Items You Might Trade
• not being bodily active. Women who are not physically active have a higher risk of breast cancer.
• Being overweight or obese after menopause. Older women who are obese or overweight have a higher risk of breast cancer than those of normal weight.
• Take hormones. Some types of alternative hormone treatments (those that include estrogen and progesterone) taken during menopause may increase the risk of breast cancer when taken for more than five years. Certain oral contraceptives (delivery control tablets) have also been found to increase the risk of breast cancer.
• Reproductive records. Having a primary pregnancy after age 30, not breastfeeding, and never having a full pregnancy can increase the risk of breast cancer.
• to drink alcohol. Research shows that a woman’s risk of breast cancer will increase with the more alcohol she drinks
Research indicates that other factors such as smoking, exposure to chemicals that can cause most cancers, and changes in other hormones due to the night shift may also increase breast cancer risk.
