No, breast cancer is not contagious
When something is said to be contagious, it means it can be transferred from one person to another. Breast cancer is not contagious as it cannot be transferred from person to person.
Breast cancer occurs as a result of abnormal and uncontrolled growth of cancer cells in the breast.
Some cases of breast cancer can be influenced by genetic factors. This is the reason why people with a family history of breast cancer have a higher risk of developing breast cancer.
Less than 10% of breast cancer is hereditary as a result of the transfer of mutated genes transfer from parent to offspring. Mutation of BRCA1 and BRCA2 are often seen in breast cancer cases. A mutated form of these genes can be inherited.
You cannot catch breast cancer when you know someone who has this condition. It cannot be transferred from one person to another simply because of touch or being exposed to the person. It should be remembered that breast cancer usually starts from within the person. It starts because there are some cells in the breast of the person that started growing abnormally.
The mutated cells will then begin to spread throughout the breast. If the mutated cells still go by undetected, that is the time when they can start to spread to other parts of the body. The only way that cancer will spread to another person is if an organ or tissue from another person who has cancer will be placed on the body of another person. Otherwise, it is not contagious.
