My wife and I are both thinking of studying in Canada, and I was wondering about the health requirements for my wife. She was recently treated for chancer. Her health has stabilized again. The doctors think they got all of the cancer, but they say there is--- statistically speaking--- a chance of a relapse in the next 4-5 years. My wife will need to get cancer screenings every six months. Is her health problem as it currently stands too serious for her to be eligible for a student visa? If she has a relapse while she's studying, can she seek treatment in Canada while she continues to study, or will her student visa be revoked for health reasons?
