So sorry to read your news, Freshheadies, but it sounds like you're getting excellent care through the Farber institute. You're young and have your cancer in an extremity, so they've already told you, I'm sure, that your prognosis is hopeful!

I'm going to let the medical cannabis resident experts address specific strains. Do you live in a medicinal cannabis state? If so, both the physician who gives you your recommendation and the dispensary can be particularly helpful in suggesting specific strains. Trying to get a specific medical strain on the street is going to be a more challenging proposition. From what I've been learning here and at school, people who use cannabis to help quell chemo/radiation symptoms generally find good anti-emetic (anti-nausea/vomiting) help from Indica or Indica-dominant strains, which also tend to help with pain. They can be more sedating, however. That's not a bad thing in your case. Don't rule out using prescription meds for the side-effects, too, because some of those work quite well.

I have a particular interest in cancer because I had a sister who had ovarian cancer. My cancer text says you'll probably be on alternate courses of vincristine, cyclophosphamide, and doxorubicin with courses of ifosfamide/etoposide mixed in, too. You can read about side effects of each of those medicines once they tell you what your specific meds will be. Hair fallout. Mouth sores. Nausea. Those'll be some of the main ones.

Here are a few links you may already have, and I apologize if you already do!

If I can be of any help in helping you translate anything you don't understand in medical literature, please let me know. I'm just a third-year med student, but I'm still very close to all the vocabulary study and am booking up in preparation for my board exams in another month or so. I'm sure your family must be worried as can be. (I have a son about your age, so it's not hard to put myself in your mom's place.) Let them do everything they can for you because, believe it or not, they need to feel like they're helping and loving you just as much as you need to feel that affection and support right now. Another thing I can recommend for both you and your family based on our experience with my sister is participation in any patient and family support groups they have at your medical institution. You're in a new club now, one not all that many people understand, and I expect you'll find that it's particularly helpful to talk to other club members when people who've not been through the disease aren't getting it.

I wish you all the luck in the world, my friend. Please let us know how you're doing!
