Welcome to the forum. I would talk with your Dr. regarding this. I would try diet modification to see if you can add weight. Discuss this with your Dr./oncologist and perhaps they can get you set up with a nutritionist.
There are cases that people are prescribed Oxandrin to aid in gaining weight/prevent weight loss, but again this is something that you should address with your treatment team.
I'm sure your friend means well, but I wouldn't follow his advice.
Best of luck and please visit out Nutrition forum. It may help you with some ideas for diet modification.
