Lung cancer metastases may travel through airways to adjacent or distant lung tissue

Lung cancer is the most common and most lethal cancer worldwide. Its prognosis remains poor: The 5-year survival rate is 6-18%. Adenocarcinoma has surpassed squamous cell carcinoma as the leading histologic type, accounting for 30% of all cases of lung cancer. Hematogenous spread (i.e., carried by blood) is the most common mechanism of intrapulmonary metastasis…

Rare cancer’s genetic pathway identified by scientists

SFU molecular biology and biochemistry professor Jack (Nansheng) Chen and three of his lab members collaborated with Chinese researchers to identify how these mutations affect genes and signalling pathways that might drive the formation of tumours in ICC. …

Egg and sperm race: Scientists create precursors to human egg and sperm

When an egg cell is fertilised by a sperm, it begins to divide into a cluster of cells known as a blastocyst, the early stage of the embryo. Within this ball of cells, some cells form the inner cell mass – which will develop into the foetus – and some form the outer wall, which becomes the placenta…

Researchers map paths to cancer drug resistance — ScienceDaily

By mapping the specific steps that cells of melanoma, breast cancer and a blood cancer called myelofibrosis use to become resistant to drugs, the researchers now have much better targets for blocking those pathways and keeping current therapies effective. The findings are published in two papers Dec…

Latest evidence on using hormone replacement therapy for treating menopausal symptoms

The review highlights that menopausal symptoms, including hot flushes and night sweats are common, affecting around 70% of women for an average of 5 years but may continue for many years in about 10% of women. Every woman experiences the menopause differently; some experience one or two symptoms mildly while others have more severe symptoms. …
