A line from Audre Lorde's book 'A Burst of Light', also known as 'The Cancer Chronicles', is circulating widely: 'Caring for myself is not self-indulgence, it is self-preservation, and that is an act of political warfare.' Lorde wrote the book while dying of breast cancer in the late 1980s, and the passage is being shared as a statement on survival and resistance.

A new study finds that infections cause roughly one in eight cancer cases worldwide. Viruses and bacteria such as HPV and H. pylori contribute to cancers that may be preventable through vaccination, screening and treatment. The findings are drawing attention to public health measures, particularly in lower-income countries where infection-related cancers are more common.

Researchers at the University of Arizona report that sex chromosomes do more than determine biological sex: they actively influence how the body handles cancer, cardiovascular disease and ageing. The findings suggest that differences in disease risk and lifespan between men and women may be rooted in genetic mechanisms, which could shape future research and treatment approaches.

Breast cancer's impact extends beyond physical illness, with patients commonly experiencing anxiety, depression and emotional distress during diagnosis and treatment. A news feature highlights the mental health toll of the disease and the importance of psychological support alongside medical care, underscoring growing attention to the emotional burden carried by patients and survivors.

Experts report that roughly one in eight cancer cases worldwide are caused by infections, such as viruses and bacteria, highlighting prevention opportunities. They stress that vaccines, including those against HPV and hepatitis B, could prevent a significant share of these cancers, renewing calls for wider vaccination coverage and infection control efforts globally.

An essay at Breakthrough Journal argues that the public is routinely told that a long list of ordinary things supposedly cause cancer, reflecting ongoing frustration with shifting and often contradictory health warnings. Readers are debating how much of cancer-risk research holds up, and why scare headlines about everyday products keep appearing despite weak or inconsistent evidence.

Sales of nitrite-free bacon are rising sharply in the UK as shoppers grow worried about the chemicals used to cure conventional bacon. Nitrites, long used to preserve and colour cured meats, have been linked by some researchers to health risks including bowel cancer. Producers are responding with alternative curing methods, and retailers are expanding nitrite-free ranges to meet demand.

New research published 1 October 2026 shows that X and Y chromosomes influence how the body handles cancer, heart health and longevity, independent of sex hormones. The findings suggest biological sex at the chromosomal level shapes disease risk, and researchers say the mechanisms could inform sex-aware approaches to medicine and treatment.
