Knowing this could potentially help doctors determine if treatment is needed up front vs. using a method called active surveillance where the disease is closely monitored over time. The study, recently published in the Journal of Urology, is the first to evaluate this risk group. https://medicalxpress.com/news/2024-08-mri-doctors-aggressive-prostate-cancer.html Wed, 07 Aug 2024 10:35:25 EDT news642245721 People who regularly eat fish or take fish oil supplements are getting omega-3 fatty acids, which play a critical role in brain function. Research has long shown a basis in the brain for aggressive and violent behavior, and that poor nutrition is a risk factor for behavior problems. https://medicalxpress.com/news/2024-05-case-omega-supplementation-aggression.html Mon, 27 May 2024 13:30:18 EDT news636035415 A protein that has been widely studied owing to its association with neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) is also linked to medulloblastoma, a type of central nervous system cancer.

Despite this substantial cancer disparity, few prospective studies focused on maximizing the recruitment of African American men have been conducted to address this problem. It is important to identify those men who are at higher risk of poorer outcomes to improve treatment management and overall survival. https://medicalxpress.com/news/2022-09-genomic-african-american-prostate-cancer.html Wed, 21 Sep 2022 16:11:27 EDT news582995483 UCLA Jonsson Comprehensive Cancer Center researchers leading a meta-analysis of seven randomized trials found an "unexpected result": Although Black men appeared to have more aggressive disease when they enrolled in clinical trials of radiation therapy for prostate cancer, their treatment outcomes and disease-specific outcomes were better than those of their white counterparts. https://medicalxpress.com/news/2021-12-higher-risk-prostate-cancer-black-men.html Wed, 29 Dec 2021 11:00:01 EST news559989493 A study led by researchers from The University of Texas MD Anderson Cancer Center found a significant association between cholesterol-lowering drugs commonly known as statins and survival rates of triple-negative breast cancer patients. Since statins are low in cost, easy to access and produce minimal side effects, this could have an important impact on outcomes for this aggressive disease. https://medicalxpress.com/news/2021-08-statins-survival-triple-negative-breast-cancer.html Tue, 03 Aug 2021 10:12:58 EDT news547204373 New prostate cancer urine test shows how aggressive disease is and could reduce invasive biopsies https://medicalxpress.com/news/2021-04-prostate-cancer-urine-aggressive-disease.html Tue, 27 Apr 2021 03:30:16 EDT news538713010 Ovarian cancer is an aggressive disease. In the UK, ovarian cancer is the 6th most common cancer for women and causes the most deaths of all the gynecological cancers. https://medicalxpress.com/news/2020-08-differences-treatment-variation-ovarian-cancer.html Wed, 12 Aug 2020 09:50:01 EDT news516441306 A new study shows more aggressive treatment may be needed for a large number of patients taking statin medications, and that treatment could help reduce cases of cardiovascular disease, the leading cause of death in the U.S. https://medicalxpress.com/news/2019-05-statin-patients-dont-healthy-bad.html Thu, 09 May 2019 17:16:31 EDT news476640982 For about 90 percent of men with prostate cancer, the cancer remains localized to the primary site, resulting in a five-year survival rate of almost 100 percent. Unfortunately, the remaining 10 percent of patients develop locally invasive and metastatic disease, which increases the severity of the disease and likelihood of death and limits treatment options. A report in The American Journal of Pathology indicates that a significantly lower presence of syntaphilin (SNPH)—a mitochondrial protein—within the tumor's central core versus at the tumor's invasive outer edge, may identify patients at increased risk of metastasis. These patients may require more rigorous testing, surveillance, and treatment. https://medicalxpress.com/news/2019-05-biomarker-men-prostate-cancer-greater.html Thu, 09 May 2019 00:00:01 EDT news476518789 Researchers at Lund University in Sweden have together with American colleagues studied deceased patients who were diagnosed with Alzheimer's disease or frontotemporal dementia.

The main finding of the study: During pregnancy, the cycle of cell division of placental trophoblasts stops after duplication of the whole genome to prevent uncontrolled growth. "Genome duplication acts like an automatic stop sign," explains study author Philipp Velicky, who conducted the study at MedUni Vienna and is currently working at IST Austria (Institute of Science and Technology – Austria). https://medicalxpress.com/news/2018-10-importance-cell-cellular-senescence-placenta.html Mon, 15 Oct 2018 08:23:36 EDT news458810610 (HealthDay)—The U.S. Food and Drug Administration says it has expanded approval for Blincyto (blinatumomab) to include adults and children with B-cell precursor acute lymphoblastic leukemia who are in remission but who still have minimal residual disease (MRD). https://medicalxpress.com/news/2018-03-blincyto-specific-leukemia.html Fri, 30 Mar 2018 08:00:02 EDT news441614105 A new score for predicting a man's genetic risk of developing aggressive prostate cancer could help guide decisions about who to screen and when, say researchers in The BMJ today. https://medicalxpress.com/news/2018-01-prostate-cancer-score-screening-decisions.html Wed, 10 Jan 2018 18:30:02 EST news434804636 Oesophageal cancer is an aggressive disease with one of the worst survival rates of all cancers.
