Breast most cancers now the main most cancers analysis

THURSDAY, February 4, 2021 (HealthDay News) – Breast cancer outperformed lung cancer as the world’s most diagnosed cancer.

In 2020 there were an estimated 19.3 million new cancer cases and nearly 10 million cancer deaths worldwide. This emerges from the Global Cancer Statistics 2020 report from the American Cancer Society (ACS) and the International Agency for Research on Cancer.

Overall, one in five people will develop cancer in the course of their life. 1 in 8 men and 1 in 11 women die from the disease.

Female breast cancer was the most commonly diagnosed cancer last year, with an estimated 2.3 million new cases (11.7%), followed by the lung (11.4%), colon (10%), prostate (7.3%) and stomach (5.6%). Cancers according to the study.

The report, published February 4 in CA: A Cancer Journal for Clinicians, looked at 10 major cancers, accounting for more than 60% of new diagnoses and more than 70% of cancer deaths.

Breast cancer has been found to be increasing in countries where rates have been historically low.

“Dramatic changes in lifestyle and the built environment have impacted the prevalence of breast cancer risk factors such as obesity, physical inactivity, alcohol consumption, postponing childbirth, fewer births and less breastfeeding,” the authors said in an ACS press release.

These factors, along with changes in times of social and economic transition, have narrowed the international gaps in cancer rates, the researchers said.

Breast cancer mortality rates were higher in transition countries than in transition countries (15 and 12.8 per 100,000), despite much lower incidence rates (29.7 and 55.9 per 100,000, respectively), the report said.

The poor outcome in these countries is largely due to later diagnosis and treatment, the authors said.

“With the implementation of evidence-based and resource-based guidelines, efforts to promote early detection and subsequent timely and appropriate treatment are urgently needed,” said lead author Hyuna Sung, lead scientist at ACS, in the press release.

Lung cancer remained the leading cause of cancer deaths in 2020, with an estimated 1.8 million deaths (18%), followed by cancers of the colon (9.4%), liver (8.3%), and stomach (7th) , 7%) and the female breast (6.9%).
