✳️Colorectal cancer is now the leading cause of cancer related death among males aged 20-39 and 40-49 ‼️It was third among 20-39 age group last year. ✳️ Concerning trend is also seen in young women; CRC related death and will likely surpass breast cancer in near future @OncoAlert

An important question I receive from my patients is that sugar fuels the cancer and whether if they need to fast or follow a low carb diet❗️This is in fact very important subject particular for patients with GI cancers @oncoalert @CrcChange @manjuggm @fireflyann . Here is why 👇.
