Different types of breast cancer tumours differ in how they affect the function of the lymph nodes. In patients with invasive breast cancer, the vessels and supporting tissue of the lymph nodes are altered, which cannot be seen in patients with a non-invasive cancer called (ductal cancer in situ). This is shown in a new study from Maria Ulvmar’s group at IGP, published online in the scientific journal Cancers.

A comprehensive study from Uppsala University, involving more than 250,000 women, shows that oral contraceptive use protects against ovarian and endometrial cancer. The protective effect remains for several decades after discontinuing the use. The study is published in the journal Cancer Research.

In the condition known as cavernoma, lesions arise in a cluster of blood vessels in the brain, spinal cord or retina. Researchers in Elisabetta Dejana's group at IGP can now show, at molecular level, that these changes originate in vein cells. This new knowledge of the condition creates potential for developing better therapies for patients. The study has been published in the journal eLife.
