Does breast cancer cause hair loss?

Hair Loss During Breast Cancer

Yes for some, it will.

But it isn't the cancer itself that causes it, but the chemotherapy treatment that some will undergo. In these cases the chance of losing your hair is very real.

Chemotherapy agents used in the treatment of breast cancer act by destroying rapidly dividing cells. Since cancers are made of rapidly dividing cells, these agents work relatively well at treating the cancer. But other cells of the body also rapidly divide. These include cells that form hair.

Whether or not your hair falls out after a chemo session depends mostly on the type and dose of medication you'll receive.
