My onoc at Dana Farber says they do not routinely check blood for Stage 1. I will ask when I see her in October and stay in touch - xoxo

I am interested in this information about melatonin. Is this something that your dr prescribed for you? I have tried melatonin for sleep issues.

@sirene My docs think 5mg of melatonin is too high! I have also been told, and read, that it is not for long term use.

Thanks for the information. My dr had said to try it for sleep problems. It helps me to fall asleep but I don't stay asleep on it.

It effects every body diferent My son can't take it either,it keeps makes him sleepy the next day

Hi all,
With respect to melatonin in the treatment of cancer, I have found more information:

- Information about Melatonin from Memorial Sloan Kettering Cancer Center https://www.mskcc.org/cancer-care/integrative-medicine/herbs/melatonin

EXCERPT
Melatonin is used to:
- Treat insomnia (trouble sleeping)
- Treat side effects of chemotherapy such as low platelet counts, weakness, and depression
- Keep blood counts from getting low due to radiotherapy
- Treat seasonal affective disorder (SAD)
- Treat migraines
- Treat insomnia in children with autism spectrum disorder

Melatonin also has other uses that haven’t been studied by doctors to see if they work.

- Melatonin and Breast Cancer: Is it Safe and Can it Help? https://www.healthline.com/health/breast-cancer/is-melatonin-safe-for-breast-cancer-patients

Please read the studies cited in the above article carefully. Many of the studies have not yet been tested on humans, but rather only in labs (in vitro) or mice (in vivo). Melatonin has potential anti-cancer properties. But the results of clinical trials in human breast cancer therapy are insufficient.

Talk with your healthcare provider before taking melatonin supplements. They can interact with some medications and affect how they work.

IMPORTANT: Talk with your healthcare provider if you have hormone-sensitive cancer like breast or prostate cancer. Melatonin can change the amount of estrogen in your body. This may worsen your condition.
