“Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects.”
I can’t tell you how many times I’ve read that statement on the informational leaflets from various bottles prescribed for me. When it comes to a disease like cancer, it might as well say, “You think these side effects are bad? Hohoho, just try not taking your meds!”
This does not give warm, fuzzy feelings of hope. Then again, there’s not much about cancer that’s warm and fuzzy.

I, admittedly, am generally accepting of the advice given by knowledgeable professionals. When my oncologist laid out a treatment plan, I didn’t argue, although when offered a choice between an effective targeted therapy versus an even more effective but also more toxic one, I opted for lower toxicity.
For me, it was a quality of life issue. If I’m “cured” of cancer but end up with severe heart problems…well, I’d rather take my chances with a less damaging option.
Cancer still remains life-threatening, now as it did decades ago. The difference is that patients are living longer and some go completely into remission. Survivorship should be considered a factor when designing a treatment plan, as should long-lasting repercussions of side effects.
So if I had one request of oncological health teams, it would be that they look beyond simply bombarding the cancer and consider the physical and mental condition in which they leave the patient, being sensitive to the possibility of ‘overtreatment’ in their exuberance to squash as much of the disease as possible.
Should you use a sledgehammer when a rubber mallet might be sufficient? Is “just to be sure” a justification for side effects than can compromise your quality of life, however long that is?

There is no “right” answer to this as everyone’s situation and risk tolerances are different. So if I could have a second request of the medical community, family and friends of the patient, it would be that they respect the limits and decisions of the one who’s going through this.
To be able to weigh the risks and decide what’s acceptable and where to draw the line — that might offer at least a semblance of control in the crazy roller-coaster ride that is cancer.
