Can you find out from your RO how many grays of radiation you are getting? The more grays it is, the more chances you will have swallowing problems. My husband got 70 grays over 7 weeks and that was the lifetime maximum. He needed his feeding tube from about four weeks into radiation. Others can tough it out and these are likely people with high pain tolerance. The other question to consider is how much do you weigh right now and can you afford to lose a large amount of weight during treatment. Start thinking along these lines and, like ChristineB said, read through the posts on feeding tubes.
