Doctor warned me against LDN – what’s your experience?

A LC doctor I visited regularly strongly advised me not to take LDN (Low Dose Naltrexone). She said: • it only blocks receptors and doesn’t really heal anything • long-term use could even cause tumors • nicotine patches would be a safer option

This really confused me, because I’ve read so many positive stories about LDN helping with fatigue, pain, inflammation etc., and I never saw anything about cancer risks.

Have you ever heard about this? What is your experience with LDN?

— Update: I forgot to mention that she also said it can be addictive and it’s hard to come off. She was frustrated that other doctors don’t care about the root cause and just prescribed me medication to mask the symptoms.
