i have read that candida can affect the glands and cause swollen lymph nodes but i am no expert at this thing. you can only go by what you research and it is hard to pick and choose what to believe and what not to believe because everyone's body is so different and can react in many different ways to this thing.
i can tell you though that i did have at one point have pains in my right armpit/gland.
my mom has swelling and pain in her glands in her throat all of the time and she is battling candida as well.
i would still definitely get some type of medical test to confirm that it is not cancer if i were you just to be on the safe side. ESPECIALLY, since you have a history of cancer.
