My Husband Was On Taxol And Carbo ( Which Is

My husband was on Taxol and Carbo ( which is a longer name) but I can't pronounce it, but he had 8 treatments along with 33 treatments of radiation for his 5 cm mass on his lung, some lymph nodes were involved, they did a CT scan with contrast after 3 weeks and the mass has shrunk half it's size, he may have to go back on Tacol with a higher dose, he had no side effects At All with the treatments, do you rethink he will gave any this time with a higher dose? The reason he gave him a lower dose is because he had heart problems and takes a lot of medication and he did not want it to affect his kidneys! My husband drank 120 ounces if water a day while on his therapy !
