Two global health observances on 1 August 2026 have drawn attention to persistent challenges in maternal and child nutrition and a changing profile of lung cancer. World Breastfeeding Week, running through 7 August, adopts the theme “Breastfeeding for a sustainable start in life: strengthen what works,” set by the World Alliance for Breastfeeding Action. The same date marks World Lung Cancer Day, first observed in 2012, which this year is accompanied by fresh evidence on environmental and third-hand smoke exposure.

India’s National Family Health Survey-6 shows that only 55.8% of infants under six months were exclusively breastfed in 2023–24, a figure that paediatricians and public health officials call a missed opportunity for immunity and long-term health programming. Barriers include weak implementation of baby-friendly hospital initiatives, insufficient counselling, workplace policies that do not support lactation, and aggressive marketing of breast-milk substitutes. Rossiclei Pinheiro, president of the scientific department of breastfeeding at the Brazilian Society of Paediatrics, warned that formula manufacturers exert “lobbying at the hospital door, on social media, in clinics” and that such ultra-processed products do not replace the dynamic, adaptive properties of human milk.

On lung cancer, oncologists in the Indian state of Karnataka reported that the disease accounted for 6.1% of all new cancers at the state-run Kidwai Memorial Institute of Oncology in 2025, with 260 of the 836 cases occurring in women. Tobacco remains the single largest preventable risk factor, but physicians in Kolkata noted a rising incidence among non-smokers and young adults, pointing to prolonged exposure to PM2.5, indoor biomass fuel smoke, and occupational hazards. A study from Clalit-Soroka University Medical Center and Ben-Gurion University of the Negev, published in Scientific Reports, found that children whose parents smoked only outdoors still had measurable urinary cotinine and experienced 67% more nighttime arousals, underscoring that third-hand smoke residues on clothing and hair disrupt sleep. In Malaysia, cardiothoracic surgeon Anand Sachithanandan observed that about half the lung-cancer patients he operates on are non-smoking Chinese women, reinforcing calls for a national screening programme.

Indonesia’s health ministry used the day to urge citizens to seek medical advice for coughs lasting more than two weeks and to use free health checks at community health centres for early detection. The dual campaigns highlight a common thread: the need for stronger preventive systems, from breastfeeding support in the first hour of life to lung-cancer screening that catches disease before symptoms appear.
