Cancer is often associated with older age, leading many people in their 20s and 30s to believe they are unlikely to develop the disease. However, an increasing number of younger adults are being diagnosed with cancer, including women who have not yet reached the age of 40 or 50.
According to the American Cancer Society’s 2025 Facts and Figures report, the trend is particularly noticeable among younger women. In 2022, approximately 1.5 young women were diagnosed with cancer for every young man. The ratio has since increased to nearly 1.8.
To understand the possible reasons behind this rise, we spoke with Dr Madhavi Nair, Consultant – Surgical Oncologist at Manipal Hospital, Varthur and Sarjapur Road. She explained several factors that may contribute to the growing number of cancer diagnoses among younger women.
5 Reasons Behind the Rise in Cancer Among Young Women
According to Dr Nair, the increase may be linked to a combination of genetic, lifestyle, environmental and hormonal factors. In some cases, however, the exact cause remains unknown.
1. Genetic Factors
Inherited genetic mutations, including changes in the BRCA1 and BRCA2 genes, can increase the risk of certain cancers. Dr Nair explained that more people carrying these inherited mutations are surviving and having children, allowing the genes to pass to subsequent generations.
2. Unknown Causes
Not every cancer diagnosis can be linked to a specific cause. Some cases are described as idiopathic when doctors cannot identify the underlying reason. This makes understanding and predicting the disease more challenging.
3. Lifestyle Habits
Dietary choices, limited physical activity, alcohol consumption, tobacco use and persistent stress may contribute to cancer risk. Delaying medical consultations and overlooking health concerns can also prevent problems from being identified promptly.
4. Environmental Factors
Environmental conditions and daily routines may also play a role. Dr Nair highlighted concerns associated with living in polluted urban areas and spending long hours in desk-based jobs with limited physical movement.
5. Hormonal Changes
Changes in reproductive patterns, including having children later in life, and the frequent use of hormonal treatments may influence hormone levels. According to Dr Nair, these changes could be associated with an increased risk of certain types of cancer.
Cancer Warning Signs Young Women Should Not Ignore
Many younger women may assume that cancer is unlikely to affect them because of their age. As a result, they might dismiss unusual symptoms or postpone seeking medical advice.
Dr Nair shared that some of her patients had noticed lumps months before consulting a doctor because they believed they were too young to be at risk. They sought medical attention only after the problem had worsened.
She advises women to pay attention to changes in their bodies and seek medical evaluation if they notice warning signs such as:
- Unexplained bleeding or unusual discharge
- New lumps or lumps that continue to grow, particularly in the breast
- Sores that do not heal
- Persistent changes in bowel movements or urinary habits
- A persistent cough or hoarseness
- Difficulty swallowing or frequent indigestion
- Changes in the appearance of moles or warts
- Unexplained weight loss or ongoing tiredness
These symptoms do not necessarily indicate cancer, but persistent or unusual changes should not be ignored. Consulting a healthcare professional can help determine whether further investigation is needed.
How Can Young Women Reduce Their Cancer Risk?
Raising awareness about cancer and encouraging open conversations about health are important steps towards addressing the growing concern. Confusion, stigma and a lack of information can prevent women from discussing symptoms or seeking timely medical care.
Dr Nair recommends adopting healthy habits and taking a proactive approach to personal health. This includes maintaining a balanced lifestyle, staying physically active and eating nutritious, high-fibre meals.
She also advises women to remain attentive to changes in their bodies and consult a doctor whenever something feels unusual rather than waiting for symptoms to worsen.
Although the rise in cancer diagnoses among younger women is concerning, greater awareness and timely medical attention can help improve the chances of detecting the disease early. Recognising potential warning signs, following appropriate screening recommendations and seeking professional advice when necessary are important steps towards better health outcomes.
