Group 1 - Smoking increases the risk of lung cancer due to harmful substances like tar and nicotine damaging lung cells, leading to gene mutations. The more one smokes and the longer the duration, the higher the risk of lung cancer. Quitting smoking can significantly reduce the probability of developing the disease [1] - Eating late-night snacks and staying up late increases the risk of stomach cancer by disrupting the biological clock and affecting the repair of the gastrointestinal mucosa. This can lead to endocrine and immune system disorders, and high stress levels can further lower immunity, increasing the risk of stomach cancer [3] - Fatty liver is a new risk factor for liver cancer, associated with obesity and diabetes. Long-term fat infiltration in liver cells can cause chronic inflammation and fibrosis, with the incidence of liver cancer rising as obesity rates increase. Weight control and metabolic regulation are crucial [4] Group 2 - Excessive or insufficient iodine intake affects thyroid health. Overconsumption of iodine (e.g., from seaweed) is linked to an increased risk of thyroid papillary cancer, while severe iodine deficiency can lead to thyroid dysfunction and increase the risk of follicular cancer. Adequate iodine intake through iodized salt is generally safe [5] - A high-fat, low-fiber diet is associated with an increased risk of colorectal cancer. High-fat diets stimulate the production of bile acids and other metabolites that can damage intestinal epithelial cells, while low-fiber diets reduce stool bulk and prolong the retention time of carcinogens in the intestines [7] - Colorectal cancer is a preventable and treatable chronic disease, with its development typically requiring a long time due to cumulative genetic damage from various pathogenic factors. There is a significant intervention window for prevention [8][9] Group 3 - Quitting smoking can prevent pancreatic cancer, as harmful substances in tobacco directly damage the pancreas, significantly increasing the risk of cancer. The earlier one quits, the more pronounced the protective effect [10] - Consuming fresh fruits and vegetables can lower the risk of throat cancer. Deep-colored vegetables like broccoli and carrots are rich in vitamins A, C, and E, which can neutralize free radicals and repair DNA damage. Daily intake of over 400 grams of various fruits and vegetables can significantly reduce the risk of throat cancer [12] - Two dietary habits contribute to esophageal cancer: consuming hot foods (over 65°C) that repeatedly damage the esophageal mucosa and eating pickled, smoked, or moldy foods that contain strong carcinogens like nitrosamines [13] Group 4 - Regular gynecological check-ups can detect ovarian abnormalities. Pelvic examinations can help identify changes in the ovaries, and combining tumor markers and ultrasound can enhance detection. High-risk individuals should start annual screenings from ages 30-35 [15] - Early vaccination against HPV is recommended to prevent cervical cancer. The vaccine is most effective when administered to girls aged 9-14 who have not yet engaged in sexual activity, with recommendations for women aged 15-26 who are HPV-free [16] - Lycopene found in tomatoes has a significant preventive effect against prostate cancer by inhibiting cancer cell division and promoting cancer cell self-destruction [17] Group 5 - Recurrent gallstones are closely related to gallbladder cancer. Patients with chronic cholecystitis, thickened gallbladder walls, or polyps larger than 1 cm are advised to undergo gallbladder removal surgery to reduce cancer risk [19] - Repeated injuries can trigger melanoma, particularly in the extremities. Continuous trauma or inflammation may stimulate skin cell carcinogenesis, suggesting that individuals in high-risk occupations should use protective gear [20] - Symptoms like headaches, vomiting, and unsteady gait may indicate neurological tumors, necessitating immediate medical attention to avoid disease progression [21] - Bone tumors are most prevalent among individuals aged 20-40, particularly in the ends of long bones. Persistent pain or swelling in these areas should be taken seriously as potential early signs of tumors [23] - Wearing sunglasses can prevent eye tumors, as UV exposure is a risk factor for various eye cancers. It is recommended to wear UV400 sunglasses in reflective environments to reduce damage [24]
