Experts Warn Delhi-NCR Toxic Air May Be Linked to Gynaecological Cancers
- •Medical experts in Delhi-NCR warn that long-term exposure to toxic air pollution and PM2.5 may contribute to the development of gynaecological cancers.
- •Prolonged exposure to fine particulate matter causes systemic biological effects such as chronic inflammation and oxidative stress, which are relevant to cancer biology.
- •A recent India-wide study revealed that women exposed to PM2.5 levels above 40 micrograms per cubic metre experienced higher odds of delayed menarche and early menopause, with stronger links in northern India.
- •While direct causation is not yet established and requires more India-specific data, experts stress that air pollution is an emerging concern for women's reproductive health.
- •Doctors advise women to focus on modifiable risk factors like maintaining a healthy weight, managing metabolic conditions, and seeking timely medical evaluation for persistent symptoms.
Key Questions Answered
Experts explain that fine particulate matter like PM2.5 can cause chronic inflammation, oxidative stress, and cellular changes, which are biological processes relevant to cancer development and hormone-sensitive tissues.
A recent study found that women exposed to PM2.5 levels exceeding 40 micrograms per cubic metre experienced a 24 per cent higher chance of delayed menarche and a 23 per cent higher hazard of early menopause, with stronger links seen in northern India.
Endometrial cancer is closely tied to obesity, prolonged oestrogen exposure, diabetes, age, and genetics, while ovarian cancer is influenced by age, family history, and inherited mutations, with pollution acting as a potential contributing concern.
