I've been doing oncology for about 20 years. Things have changed a lot. Before, we were just doing chemotherapy drugs and patients would have issues with nausea coming to the cancer center for treatments. Now, we have patients having dinner and lunch while getting chemotherapy, which is a huge change. Not only that, we are moving more and more towards targeted treatments, where we are finding out the mutations that are causing the disease process and we can attack them - and that limits side effects.
