Cancer Causes :


Cancer is caused due to damage to the structure of DNA that governs the process of cell division. This may have happened as a result of different activities like smoking, working in unhealthy circumstances etc, so that cancer causing agents or Carcinogens have entered into the bloodstream.
These carcinogens in turn cause damage or mutation in the DNA of the cell, this damage in turn activates a set of genes called “Oncogenes”. These are responsible for the rapid increase in the process of division, causing cancer.

Adenocarcinoma : According to the statics of the US cancer society about 1% of all bladder cancer cases are adenocarcinomas. The cancer cells, when observed under the microscope show many common features, when compared to the gland – forming cells of the colon cancer. Nearly all adenocarcinoma of the bladder are invasive in nature.
