Is it advisable to use Methamphetamine by a cancer patient while on treatment?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

  1. What complications could arise from breast cancer treatment (surgery, chemo, radiation, hormone therapy) if the patient is secretly using Methamphetamine?
  2. Can and should a doctor refuse treatment if they know of a patient’s meth use?

Kindly explain.

Hello,

Welcome to icliniq.com.

Methamphetamine is a CNS stimulant; it can have a lot of its own side effects. If the doctor is not aware of drug use, many of the side effects of drugs will be difficult to interpret for the doctor. Drug use can have interactions with chemo drugs and can increase the toxicity of the drug or the effect of the drug. It is a personal choice of doctor; he should refuse treatment or not.

I hope this helps.
