There was a time when talking about cancer was surrounded by fear. Decades earlier, surgeons shook heads over the idea of “young” people getting such diseases. However, today, that uneasy nod has given way to urgent discussion, not panic, about cancer across ages.

Recent research suggests that age has long been the predominant risk factor, cancers are not confined to those living under walking sticks or passing retirement golf balls. Studies from the National Institutes of Health (NIH) reveal that the incidence of early-onset cancers, those diagnosed under age 50, has risen for at least 14 types, including breast and colorectal cancers, between 2010 and 2019.

Alongside, PubMed-research confirm similar trends in younger adults under 40, with obesity-related cancers showing notable increases. “Cancer does not check your age before appearing,” says Dr. Arun Kumar Goel, Chairman, Surgical Oncology, Andromeda Cancer Hospital, Sonipat. “Yet myths persist that delay diagnosis and cost lives.” And it isn’t just older adults who are at risk, nor is it true that youth is an impenetrable shield.

Cancer undeniably becomes more common as we age, says doctor Goel, adding, “In younger populations, cancers once seen as rare now have rising trends, some doubling or climbing per year, especially where lifestyle and environmental factors are at play.” He further adds that assumptions like ‘it must be nothing’ or ‘I’m too old to bother’ are dangerous,” he warns, “The evidence we see now demands early evaluation, not assumptions.”

Dr Goel shares common cancer myths and the truths that save lives

Myth: cancer is a disease only of old age

Many still believe cancer is a badge worn only by the elderly, but increasing evidence disputes this. Research data show several cancers, such as colorectal and breast, rising in people under 50. Dr. Goel says that what matters more is symptom awareness and timely checks than counting candles on a birthday cake.

Myth: I’m too young, it can’t be cancer

This myth lulls young adults into complacency. Early cancers are often painless and subtle. Waiting for pain or dramatic signs means disease may progress unnoticed. “Pain is a late visitor,” says Dr. Goel. Persistent changes, even if mild, warrant medical evaluation.

Myth: I’m too old for treatment to help

Age does not nullify treatment benefit. Modern oncology assesses fitness, not years, before recommending therapy. Safer surgical techniques, targeted therapies, and better symptom management make cancer care feasible at advanced ages. “One isn’t ‘past help’ at 70 or 80,” Dr. Goel insists, timely care preserves quality of life.

Myth: No family history, no risk

Surprisingly, most cancers occur without a strong hereditary signal. Only about 5–10% of cases are hereditary. Lifestyle, environment, infections, and chance mutations matter greatly. Assuming immunity because of family history is a gamble many regret.

Myth: If it doesn’t hurt, it can’t be serious

Cancer’s early stages often occur silently, with subtle or no symptoms. A small lump, unexplained weight loss, or persistent odd symptom can be an early alarm. Dr. Goel stresses that absence of pain is not absence of disease, and early evaluation can be lifesaving.
