Research shows that environmental factors, lifestyle habits, and diet are key contributors to cancer risk. Dr. Hung Yung-Hsiang, a renowned renal surgeon in Taiwan, recently highlighted 10 harmful habits that could contribute to cancer development. He emphasizes the importance of quitting these habits to improve overall health. By adopting better lifestyle practices, such as healthier eating and regular exercise, you can boost your immune system and potentially stop or even reverse the progression of cancer.
10 habits Dr. Hung recommends quitting to reduce cancer risk
1. Drinking scalding hot liquids
The World Health Organization (WHO) warns that regularly drinking beverages at or above 149°F (65°C) increases the risk of esophageal cancer. Dr. Hung notes that while the mouth can tolerate temperatures up to around 140°F (60°C), repeatedly scalding the throat can damage the mucous membranes, raising cancer risk. It’s best to let hot beverages cool down before drinking.
2. Eating instant noodles from styrofoam containers
Instant noodles are convenient, but some containers are made from No. 6 plastic (polystyrene), which begins to soften at around 203°F (95°C). The high heat can release harmful chemicals if the noodles are prepared with boiling water and the container is covered tightly. For safety, it’s better to use a ceramic bowl when preparing instant noodles.
3. Consuming charred foods
Many enjoy the taste of charred meats, potstickers, or burnt toast, but charring food at high temperatures creates carcinogens, such as polycyclic aromatic hydrocarbons (PAHs). Dr. Hung also warns that starchy foods cooked at high heat can produce acrylamide, another carcinogen. To lower cancer risk, it’s advised to avoid burnt foods and eat more vegetables rich in dietary fiber.
4. Sleeping with the lights on
A study published in The Cancer Journal found that prolonged exposure to light during sleep increases the risk of thyroid cancer by 55 percent, particularly in women. Another study from the Journal of the American Medical Association linked artificial light during sleep to obesity, a risk factor for various cancers. To reduce these risks, turn off lights while sleeping.
5. Overusing CT scans
Dr. Hung cautions that frequent CT scans can expose patients to large amounts of radiation. A cranial CT equals 100 chest X-rays, while a chest CT equals 350. Studies in Circulation have shown that excessive imaging tests, particularly CT scans and cardiac catheterization, can increase cancer risk. It’s recommended to limit chest X-rays to no more than 50 annually.
6. Neglecting oral hygiene
Poor dental hygiene can contribute to pancreatic, colorectal, and oral cancers. Bacteria such as Helicobacter pylori can lead to stomach ulcers and increase the risk of gastric cancer. Dr. Hung advises brushing your teeth and gargling daily to reduce these risks and maintain oral health.
7. Frequent home renovations
The International Agency for Research on Cancer (IARC) has classified formaldehyde as a known carcinogen. Despite this, formaldehyde can still be found in many homes, even five years after renovation. Exposure to this chemical has been linked to cancer as well as respiratory issues. Dr. Hung suggests choosing low-formaldehyde building materials or using older, pre-treated furniture.
8. Eating processed meats
The IARC has classified processed meats as a known carcinogen, while red meat is considered a probable carcinogen. Dr. Hung recommends limiting processed meat consumption, replacing red meat with fish or poultry, and increasing fruit and vegetable intake to support digestive health.
9. Leading a sedentary lifestyle
Outside of sleeping, sitting for six hours or more each day is a significant risk factor for several cancers. Studies published in the European Journal of Epidemiology found that prolonged sitting increased the risk of breast, colon, prostate, rectal, and ovarian cancers. To combat this, Dr. Hung recommends using adjustable desks, taking breaks to stretch every 30 minutes, and incorporating more standing time into your daily routine.
10. Consuming too much sugar and salt
Cancer cells thrive on sugar, and a diet high in refined carbohydrates can promote their growth. Additionally, the World Cancer Research Fund (WCRF) has linked high salt intake to an increased risk of gastric cancer, particularly when combined with infections from H. pylori. Reducing your intake of sodium and high-glycemic-index (GI) foods is essential for prevention.
Conclusion
While various factors can influence cancer risks, many are within your control. By being mindful of daily habits, such as avoiding hot drinks, eating a balanced diet, and staying active, you can reduce these risks and improve overall health. Small changes today can significantly impact your well-being in the long run.
