My doctor told me that i have breast cancer, but no one in my family has ever breast cancer? why did i get it? i thought that breast cancer was inherited. she told me that it is due to changes in my genes, but i don't understand how changes in my genes can cause cancer.

Anyone can get any type of cancer, though you happen to be more likely to get it if relatives have, that is not a guarantee you are safe. Cancer occurs when some of your body's cells begin to divide and spread to other parts of your body and in surrounding tissue. Breast cancer is the cells in the breast tissue clumping together to form cancerous tumors. Though some tumors are benign, meaning they are not going to hurt you.I am sorry about the news, prayers.

because soomeone in your generation probably had it or if you got an infection wit your breast. I kw some people who asks the same questions

i am going to guess that it is co2.
