It's not news any cancer patient really wants to hear. Cancer geneticist Christina Curtis , PhD, and postdoctoral researcher Zheng Hu, PhD, have found that in breast and lung cancer patients with metastatic disease, the seeds of metastasis were often planted well before the primary tumor was diagnosed. What's more, treatments given to prevent recurrence after the primary tumor is removed -- a category of therapy called adjuvant treatments that includes chemotherapy, hormone and targeted drug therapies -- can end up promoting the growth of drug-resistant cells in the distant metastases. Curtis and Hu published their results recently in Nature Genetics.

Lung cancer was the most common type for the last two decades, but is now in second place, ahead of colorectal cancer, which is the third most widespread, Ilbawi said. Ilbawi noted that obesity in women was a common risk factor in breast cancer, and is also driving overall cancer numbers. As the global population grows and life expectancy increases, cancer is expected to become more common, rising to about 30 million new cases per year in from The coronavirus pandemic is disrupting cancer treatment in about half the countries it surveyed, Ilbawi said, pointing to delays in diagnosis, healthcare workers being under extreme stress and research being impacted.

Breast cancer survivors can be affected by a number of health problems, but often a major concern is facing cancer again. Cancer that comes back after treatment is called a recurrence. But some cancer survivors develop a new, unrelated cancer later. This is called a second cancer.
