A new study found that hairy cell leukemia survivors have an increased risk of developing certain cancers, including Hodgkin lymphoma and thyroid cancer. Meanwhile, a new test may be able to identify patients with a specific type of gene mutation that indicates an inherited form of colorectal cancer or potential response to certain drugs.
Researchers have discovered a new way to fight colorectal cancer by targeting the 'skeletons' of cancer cells, which enable them to reproduce and spread. High-dose PPARgamma inhibitors destroy cancer cell microtubules, reducing their ability to grow and metastasize.
Recent research suggests that regular statin use is not linked to lower colorectal cancer risk, while folate intake does not appear to impact breast cancer risk. However, monitoring of thyroid function may be necessary for patients taking the medication sunitinib, which can cause fatigue and hypothyroidism.
