Cancer is not a word anyone wants to hear coming from their doctor’s mouth. For anyone who has suffered cancer or is close to someone who has, they know too well how devastating it can be. While there are plenty of things we can do in our daily lives to prevent cancer, there are also things we might be doing that could unknowingly contribute to its development. These are habits to avoid to decrease your cancer risk.
48 Bad Habits That May Increase Your Cancer Risk
Cancer is a deadly disease that affects millions of people worldwide. While various factors contribute to the development of cancer, certain habits and lifestyle choices can increase the risk significantly. These are fifty habits to avoid to decrease your cancer risk. If you have already done some of these, then consider this your sign to make changes.
1. Smoking
Smoking is the leading cause of preventable cancers. The toxins in tobacco damage DNA and increase the risk of cancer in various organs, including the lungs, throat, mouth, and bladder. In fact, smoking increases your risk of developing almost every cancer. Quitting smoking can reduce your cancer risk. If you don’t smoke and aren’t planning on starting, avoid secondhand smoke as much as possible. (1)

2. Heavy Alcohol Consumption
Excessive alcohol intake can damage cells and impair their ability to repair DNA. This increases the risk of several types of cancer, including breast, liver, and colon cancer. Excessive alcohol consumption is defined as two drinks per day for women and three drinks per day for men. Beyond that amount, the risk of cancer rises significantly. (2)
3. Unhealthy Diet
A diet high in processed foods, red meat, and sugary beverages can lead to weight gain and inflammation. This increases the risk of cancers such as colorectal, breast, and pancreatic cancer. A diet high in fiber, fruits, vegetables and whole grains can help lower cancer risk. (3)
4. Obesity
Being overweight or obese can increase the risk of developing several types of cancer, including breast, colorectal, and kidney cancer. This is due to the release of hormones that promote cell growth. Obesity is also linked to inflammation, which can cause cancer. (4)
5. Sedentary Lifestyle
Lack of physical activity can contribute to weight gain, hormonal imbalance, and weakened immune system. All of these can increase the risk of cancer. It is recommended that people get at least 150 minutes of moderate-intensity exercise, such as brisk walking or swimming, each week. (5)
6. Excessive Sun Exposure
Overexposure to the sun’s harmful ultraviolet (UV) rays can cause skin damage and lead to skin cancer, including melanoma. It is crucial to use protective clothing, hats, and sunglasses. Stay in the shade when possible, and if not, use sunscreen. (6)

7. Indoor Tanning
The use of tanning beds and lamps exposes the skin to concentrated UV radiation, greatly increasing the risk of skin cancer. Do not use tanning beds to avoid increasing your cancer risk. (7)
8. Poor Oral Hygiene
Neglecting oral health can lead to gum disease, which has been linked to an increased risk of various cancers. These include pancreatic, throat, and lung cancer. Brush and floss your teeth twice per day, use mouthwash at least once per day, and be sure to visit your dentist once per year. (8)
9. Chronic Inflammation
Long-term inflammation in the body can increase the risk of cancer development. Chronic conditions such as arthritis, inflammatory bowel disease, and hepatitis can all contribute. Consuming an inflammatory diet can also increase systemic inflammation, as well as your risk of cancer. (9)
10. Excessive Processed Meat Consumption
Regularly eating processed meats like sausages, bacon, and hot dogs has been associated with an increased risk of colorectal, stomach, and pancreatic cancer. (10)
11. Poor Sleep Habits
Chronic sleep deprivation and disrupted sleep patterns can weaken the immune system and disrupt hormone regulation. This can potentially lead to an increased risk of cancer. (11)
12. Exposure to Environmental Carcinogens
Regular exposure to harmful chemicals such as asbestos, benzene, and formaldehyde can significantly raise the risk of developing various cancers. Be vigilant about mold growth in your home and be wary of what products you use, such as cleaning products or air fresheners. (12)
13. Unsafe Sex Practices
Engaging in unprotected sex with multiple sexual partners increases the risk of contracting human papillomavirus (HPV). This can lead to cervical, anal, and oral cancers. Be sure to always use condoms and get tested regularly if you are sexually active. (13)

14. Excessive Alcohol Combined with Smoking
The combination of heavy alcohol consumption and smoking significantly increases the risk of several types of cancer, including mouth, throat, and esophageal cancer. (14)
15. Using Hormonal Birth Control
Long-term use of hormonal contraceptives, such as birth control pills, can slightly increase the risk of breast and cervical cancer. Be sure to talk to your doctor about which method of birth control is best for you. (15)
16. Exposure to Secondhand Smoke
Breathing in secondhand smoke exposes non-smokers to the same harmful chemicals found in cigarettes. In some cases, it can be even worse, as smokers inhale the smoke via a filter, whereas you do not. This increases your risk of lung, throat, and other cancers. (16)
17. High Stress Levels
Chronic stress weakens the immune system and can cause systemic inflammation. It can also lead to unhealthy coping mechanisms such as smoking or excessive alcohol consumption, increasing cancer risk. Be sure to incorporate stress relieving tactics and activities into your daily routines, so that you manage stress in a healthy way. (17)
18. Poor Air Quality
Regular exposure to polluted air, both indoors and outdoors, can increase the risk of lung cancer, as well as other types of cancer. Again, be sure to watch for mold in your home and make sure the ventilation in every room is up to par. Don’t use chemical air fresheners or plug-ins. When outside, do your best to avoid walking, running, or cycling at rush hour times along busy roads with lots of traffic. (18)
19. Exposure to Radon
Radon is a naturally occurring radioactive gas that can accumulate in homes and increase the risk of lung cancer when inhaled over time. To test for radon, you can purchase a do-it-yourself kit at most hardware stores or order one online. If your home tests positive for radon, it’s recommended that you hire a professional to install an effective mitigation system and perform ongoing testing. (19)
20. Leaving a Lamp on While You Sleep
We sleep best in darkness. Exposure to dim light while sleeping at night can disrupt our endocrine system, leading to cancer. Keep all lights off in your room at night, and consider getting black-out curtains if there is too much light pollution from the street. (20)
21. Chewing Tobacco
Chewing tobacco increases the risk of oral, esophageal, and pancreatic cancer due to the constant exposure of the oral cavity to harmful chemicals. Again, avoid using this product and if you already do use it, explore ways to help you to quit. (21)
22. Excessive Pesticide Use
Regular exposure to pesticides, whether through direct contact or consuming contaminated food, has been associated with an increased risk of various cancers. Buy organic whenever possible (food, clothing, cleaning products, and more). Wash produce well before eating it. (22)
23. Overconsumption of Salt
A diet high in sodium-rich foods has been linked to an increased risk of stomach and gastric cancers. To decrease your salt intake, reduce the amount of processed and pre-packaged foods you buy. Eat out less often and avoid over-salting your food at home. (24)

24. Long-term Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) Use
Regular, long-term use of NSAIDs such as aspirin or ibuprofen has been associated with an increased risk of gastrointestinal cancers. It’s not to say that you can never use them, however, don’t let them become your first line of defense against pain. There are other ways to relieve pain, such as hot and/or cold compresses, massage, and more. Some pain can be caused by dehydration, (i.e. headaches) so be sure to hydrate well before turning to painkillers. (25)
25. Not Participating in Cancer Screenings
Failing to undergo regular screenings for breast, cervical, colorectal, and other types of cancers can delay early detection and potentially increase the risk of cancer-related complications. With all cancers, early detection is crucial to positive outcomes. (26)
26. Sleeping Near Electronic Devices
Exposure to the artificial light emitted by electronic devices at night can disrupt melatonin production and interfere with sleep cycles, potentially increasing cancer risk. Avoid screens within thirty minutes before bed and don’t keep your phone too close to you while you sleep. (27)
27. Excessive Red Meat Consumption
Consuming large amounts of red meat, such as beef, pork, or lamb, has been linked to an increased risk of colorectal and pancreatic cancer. Reduce your intake and replace it with chicken, fish, and vegetarian sources of protein such as beans and lentils. (28)
28. Using Talcum Powder
Frequent use of talcum powder in the genital area has been associated with an increased risk of ovarian cancer. If you are using this product, stop immediately and search for alternatives. (29)
29. Excessive Salt-Preserved Foods
Regularly consuming salt-preserved foods, such as pickles, salted fish, or processed meats, can raise the risk of stomach and gastric cancers. This is largely due to the salt content but also can be due to other chemicals in tins and cans and throughout the processing of these foods. (30)
30. Exposure to Diesel Exhaust
Regular exposure to diesel exhaust fumes, often on the job, can significantly increase the risk of lung cancer. Make sure to wear the protective gear necessary to protect yourself. Speak to your boss to ensure that safety standards are met. (31)
31. Neglecting Emotional and Mental Well-being
Failing to address emotional and mental health issues, such as chronic stress, anxiety, or depression, can weaken the immune system and increase the risk of cancer. Taking care of your mental health is taking care of your overall health. Reach out to a friend or seek the guidance of a therapist if you need help. (32)
32. Working Late
Long work weeks have been associated with cancer. One study found that working more than 60 hours per week can increase your cancer risk. Work-life balance is crucial for our health, so make sure that you aren’t overworking yourself. (33)
33. Eating Crackers
While not all crackers are made equal, research shows that some crackers could expose people to acrylamide, a chemical that has been linked to cancer. This will vary depending on the manufacturer, so do your research before buying, or maybe avoid eating crackers altogether. (34)

34. Prepackaged Cookies
Prep your oven, because if you want cookies, you are better off making them yourself. This is because, like crackers, pre-packaged cookies may also contain acrylamide.
35. Burning a Coal Fire
While cozying up to a warm fire in the winter is wonderful, be careful what you are burning. Coal, in particular, exposes you to fumes that can cause cancer. Stick to a wood-burning fireplace and make sure that it is well ventilated. You don’t want your living room and home filling up with smoke of any kind. (35)
36. Using Chemical Cleaning Products
Most of the regular cleaning products you can purchase in the stores are full of chemicals that can harm your health. Instead, try using homemade alternatives or look for natural products in the organic aisle. (36)
37. Too Much Time Looking at a Screen
We seem to spend our entire lives looking at screens nowadays. We scroll through videos or read the news on our phones at breakfast or on our way to work. The next six to eight hours are spent either staring at your computer screen or your phone. We then return home and sit in front of the TV watching a show or a movie before heading to bed and starting again. This is a dangerous habit for your health and your risk of cancer. Give yourself screen breaks throughout your day. In your leisure time, do things that don’t involve screens, such as board games, reading, and spending time outdoors. (37)
38. Getting an X-ray
X-rays can be a necessary part of diagnosis for broken bones and other health problems.Unfortunately, it also exposes you to DNA-damaging radiation. Speak to your health care practitioner if you are concerned about how any medical procedure or diagnostic tool may be harming your health. (38)
39. Drinking Drinks Full of Sugar
Consuming too much sugar in general is not good for our health. Sugary drinks such as sodas and many juices have been linked to higher rates of heart disease and cancer. This is especially-so for women. (39)
40. Burning Incense
If you are one that enjoys burning incense in your home, you may want to reconsider the habit. The smoke can have a negative effect on your health and cancer risk. Also, depending on the quality of the incense you are burning, you could be unknowingly inhaling unhealthy chemicals. (40)

41. Working Night Shifts
We’ve already mentioned a couple of times the impact that improper sleep can have on your risk of developing cancer. If you are in a profession that requires you to work night shifts, you are at a higher risk. Again, this seems to impact women more than men. If you are concerned about how your job could be affecting your cancer risk, speak to your healthcare practitioner about your risk and what you can do to minimize it. (41)
42. Sitting All Day
As already discussed, exercise is crucial for reducing the risk of cancer. That being said, the 150 recommended weekly minutes of moderate to vigorous exercise won’t do much if all you do is sit the rest of the time. Incorporate as much physical activity into your day as possible. Every hour, get up and walk around for five to ten minutes. Take the stairs whenever possible. Park at the back of the parking lot so that you walk more, or get off of public transport a stop or two early and walk the rest of the way. (42)
43. Excessive Cell Phone Use
An animal study suggests that excessive cell phone use can increase the risk of developing cancer. They believe that this is likely due to exposure to high levels of radio frequency radiation (RFR). Do yourself a favor and put your phone down every once in a while. (43)
44. Reusing Plastic Water Bottles
We’ve all done this one. In an effort to save on plastic bottles (and avoid spending more money), we refill a single-use water bottle several times before tossing them out. While this is helping the environment, it is not helping your health. It can increase your exposure to BPAs, which are known to contribute to cancer. If you want to protect yourself and the environment, get yourself a reusable water bottle instead. (44)
45. Some Cosmetics
Avoid all cosmetics that contain parabens and phthalates. Do your research when buying makeup and cosmetic products to ensure that they are free of harmful chemicals. Choose natural and organic products whenever possible. (45)
46. Eating Barbecued Meat
We all love a good barbecue in the summertime. Unfortunately, this method of cooking isn’t very good for your health. This is because when you cook meat at a high temperature, chemicals called PAHs and HCAs form. These chemicals have been linked to cancer in animal studies. (46)
47. Drinking Too Much Coffee
Coffee can contain acrylamide, which as we already discussed, can contribute to cancer development. Keep your coffee consumption to no more than one or two cups a day. If you need a boost beyond that, consider switching to green or black tea. (47)

48. Consuming Products Sweetened with Corn Syrup
High-fructose corn syrup is used as a cheaper alternative to sugar and honey in products around the world. Unfortunately, it is linked to many health problems, including cancer. Buyer be aware: HFCS can be found in a whole host of products, including sauces, dressings, baked goods, and more. Steer clear of the stuff by avoiding processed foods and sugary drinks. (48)
The Bottom Line
By being aware of these 50 bad habits that may increase our cancer risk, we can make informed decisions to prioritize our health and reduce the likelihood of developing this life-threatening disease. Remember that adopting healthier lifestyle choices, such as quitting smoking, maintaining a balanced diet, staying physically active, and seeking regular medical check-ups, can significantly lower the risk of cancer and improve overall well-being.
