Breast cancer is a serious disease that can affect anyone. After being diagnosed with cancer, treatment is the next step on your journey. There are several treatment options to address breast cancer, such as radiotherapy, chemotherapy, and surgery. But there are some side effects that may result from treatments and losing your appetite can be one of them. Here's a list of some useful tips to help you regain your appetite, even if you're still under treatment. 1. Experiment with Food Patients who suffer from breast cancer often experience appetite loss, including starting to dislike foods that previously tasted good. One way to address this is to try new foods, foods which differ from what would normally be eaten. However, it is important to try these while feeling good to avoid developing more food dislikes.
