Many specialists and cancer advocates are sounding the alarm over a rise in head and neck cancers, such as cancers of the throat or oropharynx, transmitted by the human papillomavirus (HPV) that is possibly linked to oral sexual habits. Are you at risk? Lack of awareness These symptoms (in red block below) are some of the early warning signs of head and neck cancers, including cancers of the mouth, lips, throat, larynx (voice box), nose, and salivary glands. Professor Jos Hille, an oral, head and neck pathologist at the National Health Laboratory Service (Tygerberg) and honorary secretary of the…

July is Bladder Cancer Awareness Month; Dr Chan updates us on all the need-to-know-bladder-cancer-info in the year 2017. Bladder cancer is the most common malignancy involving the urinary system. It is the ninth most common malignancy worldwide. There are two broad types of bladder cancer: urothelial and non-urothelial. Urothelial bladder cancer  This is the commonest histologic type in the Western world, consisting of more than 90% of all bladder cancer.

So what is Epigenetics?  “The study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself. Epigenetics has transformed the way we think about genomes.” We have no control over the genes we are born with (yet!), but we can make choices that can modify “bad genes or SNP’s” (Single Nucleotide Polypeptides). In a patient…
