1. Does sugar really feed cancer, or is that a myth?
There’s a lot of talk out there about sugar and cancer, but let’s set the record straight.
All the cells in our bodies, including cancer cells, need energy to survive. And that
energy comes from glucose, a type of sugar that fuels our bodies through a process
called glycolysis. So yes, cancer cells use glucose for energy—just like every other
cell in your body. But cutting sugar out of your diet completely won’t cure cancer.
What we do know is that being overweight, which can happen from eating too much
sugar, increases the risk of developing cancer. The key here? Moderation and
balance in your diet.
2. How much does alcohol really increase your risk of cancer?
The science is clear: Alcohol increases your risk of cancer. It’s actually the third leading preventable cause of cancer in the U.S., right behind smoking and obesity.
Even light to moderate drinking has been linked to at least seven types of cancer, including those of the mouth, throat, liver, breast, and colon. Heavy drinking makes the risks even higher. Now, some studies suggest wine drinkers may have slightly lower risks, but the truth is, it’s the alcohol itself—ethanol—that’s the problem, not the type of drink. The best way to lower your risk? Drink less, and if you don’t drink, don’t start.
3. Are all processed foods cancer-causing, or are some worse than others?
Processed and ultra-processed foods have been linked to an increased risk of cancer. But here’s the good news: Swapping out just 10% of processed foods with fresh, minimally processed options can lower your cancer risk. Studies show that making even small changes—like choosing whole foods over packaged snacks—can have a meaningful impact. The bottom line? The less processed, the better.
4. Can exercise help prevent cancer, or is that an oversimplification?
Exercise does play a role in cancer prevention—there’s solid evidence that it can lower the risk of certain cancers, like breast and colon cancer. Moving more and sitting less is key. But it’s not just about hitting the gym—everyday activities like walking, gardening, and household chores count too. The American Cancer Society recommends at least 150 minutes of moderate activity or 75 minutes of vigorous activity each week.
5. Can stress alone cause cancer, or is it just a contributing factor?
Stress is a part of life, and while it’s been suggested that it could influence cancer risk, the science isn’t clear-cut. Some studies in animals and cells suggest stress might promote cancer growth, but in humans, there’s no solid evidence that stress directly causes cancer. What we do know is that chronic stress can lead to unhealthy behaviors—like smoking, poor diet, or lack of exercise—that do increase cancer risk. Managing stress through healthy coping strategies is always a good idea.
6. Can HPV lead to cancer in men too?
Absolutely. HPV isn’t just a concern for women—it can also cause cancers in men,
including anal, penile, and throat cancers. The good news? The HPV vaccine can help prevent these cancers.
7. Why does cancer treatment cause hair loss, and does it always grow back the same?
Chemotherapy targets fast-growing cells—including hair follicles—which can lead to hair loss. Most of the time, hair grows back after treatment, but it may look different in color or texture.
8. How can patients manage weight changes during treatment?
Sudden weight gain or loss is common, and the best approach is working with a registered dietitian to create a personalized plan. Small, frequent meals and staying active as tolerated can make a big difference.
9. Is it normal to feel disconnected from your body after surgery like a mastectomy?
Yes, and it’s completely understandable. Major surgeries can change how you see yourself. Therapy, support groups, and reconnecting with your body through movement can help regain confidence.
10. Why is depression so common in cancer patients, and how can it be managed?
A cancer diagnosis can turn life upside down, and it’s normal to feel overwhelmed. Depression is common, but it’s treatable. Seeking support from mental health professionals, staying socially connected, and staying active can help manage these feelings.
11. How can friends and family support a loved one’s mental health during treatment?
Sometimes, just being there and listening can make all the difference. Offer practical help, check in regularly, and encourage them to talk to professionals if needed.
12. How does the fear of cancer coming back affect mental health?
The fear of recurrence is real and can be overwhelming. Staying informed, practicing mindfulness, and focusing on what you can control—like healthy habits—can help ease that fear.
13. Does surviving cancer ever feel like a loss as much as a victory?
For many, surviving cancer comes with mixed emotions—gratitude for life but also a sense of loss for what’s changed. Acknowledging these feelings and seeking support can help navigate this complex experience.
