Canadian high school student improves experimental cancer treatment
A Canadian high school student has improved an ineffective experimental cancer therapy with a simple tweak — pairing it with antibiotics — earning accolades from a panel of eminent scientists on Tuesday. Cancer “photothermal therapy” — or PTT — involves injecting a patient with gold nanoparticles. These then accumulate in…
Scientists used modified T-cells to wipe out childhood leukemia in a little girl
US researchers on Monday reported encouraging success with a new type of immune cell therapy that wiped out leukemia in a young girl by using her own modified T cells to fight the cancer. The case study of Emily “Emma” Whitehead, age 7, offers hope for a new path against…
Study: Chemotherapy can backfire and boost cancer growth
Cancer-busting chemotherapy can cause damage to healthy cells, which triggers them to secrete a protein that sustains tumor growth and resistance to further treatment, a study said Sunday. Researchers in the United States made the “completely unexpected” finding while seeking to explain why cancer cells are so resilient inside the…
Researchers find cancer stem cells that cause tumor regrowth
Researchers presented evidence Wednesday for the existence of cancer stem cells, with three different studies seeking to end a decades-old scientific dispute about how tumours grow. The discovery should lead to new drugs targeting stem cells that cause tumours to reappear after cancer therapy, the teams argued in three scientific…
Blood test ‘can save breast cancer patients’ lives’
A simple blood test can save lives by helping doctors swiftly diagnose whether a patient with early breast cancer faces high risk of death or relapse after treatment, specialists said Wednesday. Tumour cells in a blood sample, when taken at an early stage of the disease, are an accurate predictor of a patient’s survival chances, the team…
Study on mice shows fasting weakens cancer
WASHINGTON — Early research on mice with cancer shows that fasting may weaken tumors and help chemotherapy work better, scientists said on Wednesday. While it remains unknown if the same approach could work in humans, or if it would even be safe, researchers said the findings suggest a promising new…
Scientific community abuzz regarding potential cancer breakthrough
US researchers said Monday they have discovered how to keep tumor cells alive in a lab, generating buzz in the scientific community about a potential breakthrough that could transform cancer treatment. Until now, scientists have been unable to make cancer cells thrive for very long, or in a condition that…
PBS documentary sheds light on marijuana’s cancer-killing properties
The cancer-killing properties of marijuana were the subject of discussion in a PBS documentary that aired this week to little media fanfare. While using marijuana to kill cancer may sound like a wild claim to some, it struck Dr. Prakash Nagarkatti as a great idea. In his studies as professor…
