New Delhi: The complexities of cancer have given rise to numerous myths and misconceptions over the years. While some myths are harmless, others can cause unnecessary fear or promote ineffective and even harmful behaviours. Let’s debunk some common myths about cancer and separate fact from fiction.
In an interaction with News9Live, Dr. Kunal Sharma, Associate Director & HOD, (Centre of Excellence – Histopathology), Agilus, listed the commonest myths associated with cancer and shared the facts instead.
“Understanding the truth about cancer is crucial for both prevention and treatment. Misinformation can lead to anxiety, poor health choices, missed opportunities for early detection and faulty management. Regular screenings, a balanced diet, a healthy lifestyle, and consulting medical professionals for accurate information are essential steps in effectively managing cancer risk. Stay informed, stay healthy, and don’t let myths dictate your understanding of cancer,” said Dr Sharma.
Myth 1: Cancer is Always Hereditary
Fact: While a family history of cancer can indeed increase your risk, not all cancers are hereditary. According to the American Cancer Society, only about 5%-10% of cancers are due to inherited genetic mutations. The majority of cancers are caused by environmental factors, lifestyle choices, and random mutations.
Myth 2: Cancer is a Death Sentence
Fact: Modern medicine has made incredible strides in cancer treatment and early detection. Many cancers, especially when caught early, are treatable and even curable. For instance, the five-year survival rate for breast cancer is now about 90%, and for prostate cancer, it’s more than 95%. Early detection through regular screenings is crucial.
Myth 3: Only Smokers Get Lung Cancer
Fact: While smoking is the leading cause of lung cancer, non-smokers can develop it too. Approximately 10% to 20% of lung cancers occur in non-smokers. Factors such as exposure to radon gas, passive smoking, and other environmental pollutants also contribute to lung cancer risk.
Myth 4: E-Cigarettes Are Completely Safe
Fact: E-cigarettes can contain harmful substances and may increase the risk of lung-related issues and potentially cancer.
Myth 5: Only Heavy Drinking Causes Cancer
Fact: Even moderate alcohol consumption can increase the risk of certain cancers, including breast, liver, and esophageal cancer.
Myth 6: Smoking Marijuana Does Not Affect Cancer Risk
Fact: Marijuana smoke contains carcinogens, similar to tobacco smoke, and can increase the risk of lung cancer, though more research is needed.
Myth 7: Quitting Smoking or Drinking is Useless After Years of Use
Fact: Stopping smoking or drinking at any point lowers your risk of cancer and improves overall health and even survival post disease occurrence.
Myth 8: Sugar Feeds Cancer
Fact: While it’s true that cancer cells consume more glucose than normal cells, there’s no direct evidence that sugar intake causes cancer to grow faster. However, a diet high in sugar can lead to obesity, which is a known risk factor for various types of cancer.
Myth 9: Cancer Treatments Are Worse Than the Disease
Fact: Cancer treatments can have significant side effects, but they are continually improving. Newer therapies, such as targeted therapy and immunotherapy, preferentially act on the cancer cells and aim to spare healthy cells, thereby carrying lesser side effects and resulting in improved quality of life. Early-stage cancers can often be treated more conservatively, reducing the side effects further.
Myth 10: Cancer Always Causes Pain
Fact: Not all cancers cause pain, especially in their early stages. Pain can develop later on as the disease progresses. Early detection and treatment are key to managing symptoms efficiently.
Myth 11: Natural Therapies Can Cure Cancer
Fact: While some natural therapies might complement conventional treatments and help manage symptoms, there’s no scientific evidence that they can cure cancer. Always consult your doctor before starting any alternative treatment.
Myth 12: Cell Phones Cause Cancer
Fact: Extensive research has yet to confirm a direct link between cell phone use and cancer. The World Health Organization classifies radiofrequency electromagnetic fields as possibly carcinogenic, but no definitive proof exists.
Myth 13: Cancer Only Affects Older People
Fact: Cancer can occur at any age. While the risk increases with age, various cancers such as leukemia, bone cancer, and some brain tumors are more prevalent in children and young adults.
While a family history of cancer can indeed increase your risk, not all cancers are hereditary. According to the American Cancer Society, only about 5%-10% of cancers are due to inherited genetic mutations. The majority of cancers are caused by environmental factors, lifestyle choices, and random mutations.
