  2. Circulating tumor cell - Wikipedia

    en.wikipedia.org/wiki/Circulating_Tumor_Cell

    The cancer exodus hypothesis suggests that CTC clusters remain intact throughout the metastatic process, rather than dissociating into single cells, which was previously assumed. According to this hypothesis, the clusters enter the bloodstream, travel as a cohesive unit, and exit circulation at distant metastatic sites without breaking apart.

  3. Continuously variable transmission - Wikipedia

    en.wikipedia.org/wiki/Continuously_variable...

    A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios, typically resulting in better fuel economy in gasoline applications. [1] This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps.

  4. Clonally transmissible cancer - Wikipedia

    en.wikipedia.org/wiki/Clonally_transmissible_cancer

    A transmissible cancer is a cancer cell or cluster of cancer cells that can be transferred between individuals without the involvement of an infectious agent such as an oncovirus. [ 1 ] [ 2 ] The evolution of transmissible cancer has occurred naturally in other animal species, but human cancer transmission is rare. [ 2 ]

    On April 11, 1986, a patient was to receive electron treatment for skin cancer on the face. The prescription was 10 MeV for an area of 7x10 cm. The operator was the same as the one in the March incident, three weeks earlier. After filling in all the treatment data she realized that she had to change the mode from X to E.

  6. Cancer cell - Wikipedia

    en.wikipedia.org/wiki/Cancer_cell

    Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. [1] Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because ...

  7. Causes of cancer - Wikipedia

    en.wikipedia.org/wiki/Causes_of_cancer

    Generally, it is believed that the cancer arises, or a pre-existing cancer is encouraged, during the process of repairing the trauma, rather than the cancer being caused directly by the trauma. [83] However, repeated injuries to the same tissues might promote excessive cell proliferation, which could then increase the odds of a cancerous mutation.

    He’s also a longtime fundraiser for cancer research, helping friend Jim Valvano to the stage at the 1993 ESPYs, where Valvano delivered his famous “Don’t give up” speech. Valvano died of ...

  9. BRCA mutation - Wikipedia

    en.wikipedia.org/wiki/BRCA_mutation

    However, since pancreatic cancer is relatively rare, people with a BRCA2 mutation probably face an absolute risk of about 5%. Like ovarian cancer, it tends not to produce symptoms in the early, treatable stages. Like prostate cancer, pancreatic cancer associated with a BRCA mutation tends to appear about a decade earlier than non-hereditary ...
