Is colon cancer metastasized to the lungs contagious?

Due to irregular lifestyles, environmental pollution, and poor diet, the number of people with colorectal cancer is increasing. I believe many people have the same question as me: is colorectal cancer contagious when it metastasizes to the lungs? The answer is no. Colorectal cancer is not contagious. Usually, general cancers are not contagious, but everyone should still pay attention to the fact that some carcinogenic viruses are contagious, such as the hepatitis B virus that causes liver cancer. Let's take a look at the specific related situations.

First of all, we know that colorectal cancer is not contagious because cancer cells are not contagious, but some carcinogenic viruses are contagious, such as the hepatitis B virus that causes liver cancer, Helicobacter pylori that causes gastric cancer, and the Epstein-Barr virus that causes nasopharyngeal cancer. These need to attract everyone's attention.

Secondly, although colon cancer is not contagious, some familial tumor syndromes, such as hereditary non-polyposis colon cancer, can significantly increase the chance of colorectal cancer, and the onset time is younger. If family members find themselves feeling unwell, they must seek medical attention as soon as possible to avoid delaying the best time for treatment.

Finally, generally speaking, cancer presents a variety of symptoms, but there are only two carcinogenic factors: one is external factors, including: ionizing radiation, chronic inflammatory stimulation, mold, virus and parasites, etc.; the other is internal factors, including: genetic factors, secretory factors, immune function and mental factors. Knowing this, people can do a better job of prevention and try to avoid the occurrence of cancer.

Pay attention to maintaining good living habits, avoid bad habits such as smoking and drinking, exercise appropriately, eat a balanced diet, avoid irritating and fried unhealthy foods, and pay attention to going to the hospital for regular physical examinations.
