Question

Does cancer cause baldness???

Answer 1

Yes and no.

Hair loss in cancer patients is typically caused by the cancer treatment, not the disease itself.
Chemotherapy, radiation, and other treatments commonly result in differing degrees of hair loss.
As the drugs destroy cancer cells, they also harm the hair follicles, leading to hair loss.

Short answer:
No, cancer does not cause it, the treatment does.

Answer 2

No however chemo does.
