Scientists have discovered the switch to harness the power of cord blood and potentially increase the supply of stem cells for cancer patients needing transplantation therapy to fight their disease. 
Stem cells were first discovered in Toronto in 1961 at the
Princess Margaret Cancer Centre
 by Drs. James Till and Ernest McCulloch, a discovery that launched a new field of science and formed the basis of all stem cell research that continues to this day. 

Cancer centers promoting their services dramatically increased their advertising spending from 2005 to 2014, and  9 of the 20 that accounted for the bulk of the spending were National Cancer Institute-designated centers, so they were using taxpayer funding to advertise to taxpayers to get taxpayers to come to their centers.  Five were for-profit institutions.

Magnetic Resonance Imaging (MRI) is useful in detecting breast tumors and in cancer evaluation but its current pre-operative use in breast conserving surgery isn't helping patients as it should. 

Traditionally, patients who are scheduled to undergo breast-conserving lumpectomy for breast cancer undergo a breast MRI prior to surgery to help inform the surgeon about the size, shape, and location of the tumor. The issue is that MRIs are performed with the patient lying face down, but then the surgery is performed with the patient lying face up. 

Glioblastomas are often resistant to the one type of drug that breaks the blood-brain barrier. HealthHub You find yourself sitting in your doctor’s surgery. It’s only been a few days since your initial visit to check on these pounding headaches you’ve been waking up with, along with some dizziness, nausea and vomiting, and a general drowsy and disconnected feeling.

Chimeric antigen receptor (CAR) T cell therapy, which edits a cancer patient's T cells to recognize their tumors, has successfully helped patients with aggressive blood cancers but has yet to show the ability to treat solid tumors. To overcome this hurdle, researchers genetically engineered human T cells to produce a CAR protein that recognizes a glycopeptide found on various cancer cells but not normal cells, and then demonstrated its effectiveness in mice with leukemia and pancreatic cancer. Their proof-of-concept study appears June 21 in Immunity.

People with cancer are often told by their doctors approximately how long they have to live, and how well they will respond to treatments, but what if there were a way to improve the accuracy of those predictions?

A new method could help, using data about patients' genetic sequences to produce more reliable projections for survival time and how they might respond to possible treatments. The technique is an innovative way of using biomedical big data -- which gleans patterns and trends from massive amounts of patient information -- to achieve precision medicine -- giving doctors the ability to better tailor their care for each individual patient.

Acute Myeloid Leukaemia (AML) is not a single disorder, but at least 11 different diseases, and that genetic changes explain differences in survival among young AML patients, according to a new study on the genetics of AML in New England Journal of Medicine.

Up to 25 percent of of lung cancer patients also have autoimmune disease, which may make them unsuitable for increasingly popular immunotherapy treatments.

Men with low levels of the male sex hormone testosterone need not fear that testosterone replacement therapy will increase their risk of prostate cancer, according to an analysis of more than 250,000 medical records.

In the study, researchers found that, as a group, men prescribed testosterone for longer than a year had no overall increase in risk of prostate cancer and, in fact, had their risk of aggressive disease reduced by 50 percent.

With a cure rate approaching 90 percent, acute lymphoblastic leukemia (ALL), the most common type of childhood cancer, is one of the big "success stories" of modern cancer treatment.

Yet up to 20 percent of patients with a high risk of relapse are not cured, which could change with the results from a clinical trial showing that high doses of the commonly-used chemotherapy drug methotrexate increases the survival rate for these patients.
