Common misconceptions about cancer: a guide to understanding the facts

During China’s “National Anti-Cancer Week” from April 15 to 21, China Daily addressed common misconceptions about cancer. One myth is that dying hair, eating overcooked eggs, and staying up late can cause cancer. Experts clarify that there is no special food or product that can prevent cancer, and patients should follow their doctor’s advice regarding treatment and nutrition.

Another myth is that staying up late causes liver cancer. While it can affect the immune system and liver function, it is not a direct cause of cancer. Proper nutrition, on the other hand, can benefit cancer patients by improving their resistance and reducing side effects of treatment. There is no scientific basis to limit nutrition for cancer patients, and they are encouraged to include high-quality protein and fresh fruits and vegetables in their diet.

Some people believe that a biopsy can cause cancer to spread, but experts assure that modern aspiration procedures are designed to prevent this. Similarly, drinking coffee in normal amounts does not significantly increase the risk of cancer, despite the presence of acrylamide in coffee and other foods cooked at high temperatures. The formation of a “gray” layer on overcooked eggs is simply a chemical process and does not cause cancer.

Hair dye containing p-phenylenediamine may pose a small cancer risk with excessive exposure, but there is no evidence that moderate use increases the risk. Cancer can be effectively treated with modern medical technology, and early detection can significantly improve outcomes. Different cancers in the urinary system can present with various symptoms, and not all hepatitis B carriers will develop liver cancer.

Overall, it is important to debunk common misconceptions about cancer and seek accurate information from experts to prevent unnecessary anxiety and fear.
