Major Cancer Myths 彙整 - HK Cancer Fund

1.No-one in my family has cancer, so I must be risk-free

While some cancers are hereditary, most cancers are caused by genetic changes that take place as a result of ageing and exposure to environmental factors, such as tobacco smoke. Other factors, such as your diet and level of physical activity, may also influence your risk of developing cancer.

2.Eating ‘superfoods’ can prevent cancer

The word “superfood” is a marketing term used to describe foods that have special health benefits, and that are often claimed to prevent cancer. While some of these foods do have specific health benefits, it is unlikely that any single food alone can make a significant difference to your cancer

3.Deodorants can cause breast cancer

There is no scientific evidence to suggest that this is true.

4.UV rays will not harm my skin on a cloudy day

As much as 80 percent of the sun’s ultraviolet rays can penetrate through clouds. Just because you can’t see the sun, does not mean harmful UV rays can’t cause damage to your skin.

5.Sugar ‘feeds’ cancer cells

7.If you have no symptoms, you don’t have cancer

In its early stages, cancer often has no symptoms and can go unnoticed. Signs of cancer are usually first detected by a doctor during a routine check-up. Be aware of your body and the common symptoms of cancer along with early detection tests and how often they should be performed

8.Breast cancer only affects women not men.

While breast cancer is most common in women, there are still a small percentage of men who are diagnosed with this type of cancer. Men with breast cancer often present with a more advanced disease stage primarily due to lack of awareness and delayed diagnosis. Like women, men should check

9.There are herbal products that can cure cancer?

Although complimentary therapies have been shown to help patients cope with the side effects of cancer treatment, no herbal products have been clinically proven to effectively treat cancer. Some herbal remedies may even react harmfully when taken during your cancer treatment, and therefore you should always discuss any complimentary medicines

10.Mammograms are dangerous and not worth the risk.

Although not always 100% reliable in picking up all breast cancers, when performed regularly (yearly screenings are recommended for women over the age of 40), mammograms can provide early detection of breast cancer for most women and this can save lives. Mammograms require very small doses of radiation and the
