Cancer Research: Nanotech drug delivery shows promise for improved melanoma treatment ♦ Aspirin use may lower breast tissue density allowing for earlier detection

Obesity contributes to metastasis in ovarian cancer patients An increased body mass index is associated with a greater risk for ovarian cancer with worse overall survival, a large number of studies have shown. However, the influence of obesity on ovarian cancer metastasis had not been evaluated. Researchers set out to determine are tumor cells better able to successfully metastasize when the "host" is obese versus lean?
Older Breast Cancer Patients Defy Survival Models Older women with early-stage, invasive breast cancer had better survival rates than what was estimated by a popular online tool for predicting survival.
Aspirin use does not improve outcomes for cancer patients, but may lower breast tissue density, allowing for earlier detection Whether aspirin may help prevent or reduce the risk of breast cancer remains a hotly debated research question. While past studies have indicated a potential benefit, most recently in hormone receptor-positive breast cancers, one new study suggests otherwise. Aspirin does not appear to be protective or associated with improved clinical outcomes or survival among breast cancer patients with aggressive disease However, another study suggests aspirin may in fact help reduce breast tissue density, which could lead to earlier detection.
Nanotech drug delivery shows promise for improved melanoma treatment A new three-drug delivery system for cancer treatment, especially metastatic melanoma, the deadliest form of skin cancer, has been developed by researchers. The work has demonstrated that the system may have particular value with cancers like this that often spread through the lymphatic system. It may offer a novel therapeutic option for more effective cancer treatment.
