Can chemotherapy cause cancer?

I'm about to start chemotherapy for my cancer, and I've been reading up on it. Someone told me that in very rare cases, chemotherapy itself can actually cause a new cancer to develop. Is there any truth to this?

Talk about irony! But yes, chemically speaking, some chemo drugs can rarely increase the risk of developing a second cancer years down the line. However, the immediate risk of not treating your current cancer is far higher, so don't let this stop you.

Every medicine has its dual nature, my friend. While chemo is powerful enough to cure, in rare cases it can cause secondary issues later. Keep your thoughts positive, focus on healing right now, and let the doctors guide your path safely.

Oh my god, I read about this online and it gave me so much anxiety! Yes, there is a very small risk of secondary cancers from chemo, but please don't let these thoughts consume you. The doctors measure the benefits very carefully before starting treatment, so trust them.

Having just completed my chemotherapy, I had this exact same doubt. My oncologist explained that yes, secondary cancers (like leukemia) are a rare, known risk years later because of the DNA damage. But the risk is extremely small compared to the immediate life-saving benefits of clearing your current cancer.

I can't offer medical advice, but when my grandfather was undergoing chemo, his oncologist explained that while there is a very minimal risk of a secondary cancer in the future, curing the existing cancer was the absolute priority. We chose to trust the doctor's plan.
