How Is Breast Cancer Transmitted
It's not: Breast cancer is not transmitted from one person to another. It starts as a normal cell in the breast. The cell is damaged and instead of dying, it starts dividing, making more damaged cells that also divide. That's breast cancer in a nutshell... Breast cells that keep dividing and don't stop. ...Read moreSee 1 more doctor answer
Breast cancer results when glandular cells lining the milk ducts and lobules of the human breast begin to grow in an unregulated manner. The growth occurs initially inside the ducts but eventually breaks outside into the breast tissue and ultimately spreads both to the lymph nodes in the armpit and via the bloodstream to other parts of the body. Because of the promoting affect of estrogen almost all breast cancer occurs in women and is a rarity in men. The unregulated growth is due to both inherited and acquired genetic defects. It is the most common malignancy in women but it often curable if found early and treated effectively with surgery, hormonal therapy, chemotherapy and targeted therapy, or a combination thereof. Early detection before the malignancy becomes large enough to be felt depends on mammography/sonography and MRI imaging of the breast ...Read more
Not transmitted: It is essential that you know that breast cancer is not "transmitted" like an infectious disease. It is not contagious (though there is a mouse form that is passed mother-to-daughter). A woman develops breast cancer through mutations over the course of many years. Hope this is the answer you sought, and good luck. ...Read moreSee 1 more doctor answer
Maybe none: Early breast cancer has no signs or symptoms. Breast cancer may later present as a painless firm breast lump. Rarely changes in color of the skin, sometimes nipple will get retracted or breast skin pulled inward. Best is to have yearly physical examination and mammogram after age 40 before these symptoms occur. Any breast lump, painful or not, should be examined by your doctor. ...Read moreSee 2 more doctor answers
A lump in the breast: This is how most women discover their breast cancer. However most such lumps turn out to be benign. If you do monthly breast self exam, you will be able to tell if you have any new lumps. They are often painless and grow in size if left unattended for more then 1 or 2 months. The tumor can also spread outside of the breast if not treated. Promptly. ...Read more
Sometimes.: It is estimated that approximately 10-15% of all breast cancers in the US are of the hereditary type. These genes can be inherited from either your father or your mother. If a woman inherits this gene, they have a 50-75% chance of developing breast cancer in their lifetime. These cancers tend to occur at any earlier age and may occur in both breasts. ...Read moreSee 2 more doctor answers
Not directly: Breast cancer is not directly passed from parent to child. However, an increased risk of developing breast cancer can be inherited. Mutations in the genes brca1 and brca2 increase your chance of developing breast cancer. You are not 100% guaranteed to get breast cancer if you inherit these genes, but the risk can be as high as 85%. ...Read moreSee 2 more doctor answers
Sometimes.: It is estimated that 10-15% of all breast cancer cases in the us occur due to hereditary factors. This risk may be identified by doing a simple blood test to check for brca mutations. We generally advise testing family members with known breast cancers first before checking unaffected family. ...Read moreSee 2 more doctor answers
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
