谁能帮我写一篇英语小短文?要有明确的主题的 阅读时间在3分钟左右!

Today I had an internship at the cancerology department of my faculty.Of all the patients I ever encountered during my internships,I were the most affected by patients suffering from cancer and who had almost no hope of returning back to a normal life.This led me to ponder on the question of how our nutrition and lifestyle has changed drastically over the centuries and how cancer can be avoided.Today you have more fatty,sugary foods,animal meats doped with hormones and steroids and cultivations sprayed with insecticides and pesticides.All these contribute to the formation of cancers.So how to decrease the risks of cancer?
