If a patient has breast cancer and breastfeeds her child, do the stray cancer cells in the milk have any effect on her child?

Unlikely: The stray cancer cells in breast milk of a woman with breast cancer are not likely to be viable. Even if viable, such cells are likely to get digested in the stomach. However, it is probably not a good idea to feed a baby on the breast that is known to have cancer as cancer tissues often release products that are not healthful and may be harmful.

NO: Studies cancer cell will not pass into milk and will not give cancer to the child even in later part of life . However doctors will not recommend breast feeding , the medication , radio isotopes will pass into milk and effect the child..
