Cancer cells, however, have the ability to grow without these external signals. There are multiple ways in which cancer cells can do this: by producing these signals themselves, known as autocrine signaling ; by permanently activating the signaling pathways that respond to these signals; or by destroying 'off switches' that prevents excessive ...
A newly identified colon cancer gene may drive the disease by making the environment in the vicinity of tumors more hospitable to them, researchers say. Why does colon cancer grow so fast? Study ...
The rise of colorectal cancer among people under 50 in the U.S. has had experts worried for years — and new research shows how the ominous trend has spread globally. Colorectal cancer is surging ...
Cancer cells have unique features that make them "immortal" according to some researchers. The enzyme telomerase is used to extend the cancer cell's life span. While the telomeres of most cells shorten after each division, eventually causing the cell to die, telomerase extends the cell's telomeres. This is a major reason that cancer cells can ...
J ust this month, two young, high-profile public figures announced that they have cancer. First, Olivia Munn, 43, disclosed that she was treated for breast cancer after catching it early.
The cancer stem cell model, also known as the Hierarchical Model proposes that tumors are hierarchically organized (CSCs lying at the apex [6] (Fig. 3).) Within the cancer population of the tumors there are cancer stem cells (CSC) that are tumorigenic cells and are biologically distinct from other subpopulations [7] They have two defining features: their long-term ability to self-renew and ...
After five years, 529 of the participants were diagnosed with colorectal cancer, also known as bowel cancer. People who were active in the morning and evening had an 11% lower risk of developing ...
Although there are over 50 identifiable hereditary forms of cancer, less than 0.3% of the population are carriers of a cancer-related genetic mutation and these make up less than 3–10% of all cancer cases. [3] The vast majority of cancers are non-hereditary ("sporadic cancers"). Hereditary cancers are primarily caused by an inherited genetic ...
