How long does it take for cancer to develop?I’ll give you a time frame. Get ahead of time

In fact, everyone has cancer cells, because cancer cells are transformed from normal cells by mutations. When normal cells become cancer cells, they divide beyond the control of the body, resulting in cancer.Cancer cells are very aggressive and can invade and destroy adjacent tissues and organs.Cancer cells can also jump out and enter the blood and lymphatic system, where they can spread to other sites and form new tumors, making treatment more difficult.It can be seen that cancer cells are not formed overnight, how long does it take for cancer to form?How long does cancer take to form?Having just one or two cancer cells in the body does not cause cancer because the immune system is constantly watching and killing cancer cells.In some cases, however, the immune system can’t kill all the cancer cells, and cunning cancer cells can escape the immune system and multiply uncontrollably in the body, leading to cancer.Cancer cells are caused by mutations in normal cells, and the process is influenced by a variety of factors, including genetics, environmental psychosis and bad habits.As cancer cells continue to divide and multiply, they are discovered when they grow to more than one centimeter.When diagnosed with cancer, the cancer cells have been dividing in the body for a long time.There is no specific answer to how long it takes for cancer to develop, and it varies widely by type and site.Some cancers take years or more to develop, such as stomach and thyroid cancers, which grow slowly.Some cancers grow rapidly, such as small-cell lung cancer, where small lesions develop and metastasize rapidly in just a few months.How can cancer be found?Almost all cancers have no typical symptoms in the early stage. If you want to find early cancer, you can only go to the hospital regularly to do cancer screening.Workers with long-term smoking, a family history of lung cancer, long-term exposure to harmful gases, and patients with chronic lung disease should go to hospital regularly for low-dose spiral CT screening of the chest;People with chronic enteritis, intestinal polyps, obesity, and a family history of colorectal cancer should have regular colonoscopy to screen for colorectal cancer.Patients with chronic hepatitis B or chronic hepatitis C should have regular examination of liver b-ultrasound and alpha-fetoprotein, etc.Different cancers have different screening methods, high-risk groups should be targeted to choose cancer prevention physical examination programs.What factors affect the occurrence and development of cancer?1. Immunity with perfect immunity can fight against mutated cancer cells. When the cells become cancerous, immune cells can kill them, or live in peace with the immune system, so that patients can live with tumors for a long time.The degree of malignancy of liver cancer, small cell lung cancer and pancreatic cancer is high, which can take precious lives in a short period of time.Some cancers, such as those of the thyroid and prostate, are slow-growing and have little impact on life expectancy if they are actively treated early.Warm prompt many cancer occurrence is concerned with acquired factors, so life intervention should be done well.Eat a diversified, balanced and comprehensive diet. Eat more high-quality protein and multivitamin foods, such as eggs, milk, fish and lean meat, fresh fruits and vegetables, and whole grains, and avoid pickled and over-processed foods.Smoking and drinking, bad mood and staying up late will affect body function, so we should correct bad habits in time, stay away from cigarettes and second-hand smoke, do not touch alcohol;Do the combination of work and rest, avoid overwork;Keep calm;Sit less and move more to get at least 150 minutes of physical activity a week.Family doctor online special article, shall not be reproduced without authorization
