What are Cancer Cells? Cancer cells are immortal cells that divide continuously. These cells normally form solid tumors or flood the blood with abnormal cells. They can be classified based on their origins in the human body, such as epithelial cancer cells, blood cancer cells, immune system can...
Proto-oncogenes are important cellular genes which can acquire gain in function mutations as random events in somatic cells. In their mutated, activated forms they are called cellular oncogenes or c-oncs. This distinguishes them from homologous DNA sequences captured by viruses from host cells in...
What are Precancerous Cells? What are HeLa Cells? What is Cell Lysis? What are Atypical Squamous Cells of Undetermined Significance? Discussion Comments Byartlover— On Jan 30, 2011 @abundancer -- I know of a doctor who treats atypical squamous cells of the vaginal area with a topical crea...
Cells in the body are growing all the time. As they wear out and disappear, their places are taken by new cells of exactly the same kind. But cancer cells look and act differently from normal body cells. They look like the young cells of the part ...
What Is Cancer Cancer is actually a group of many related diseases that all have to do with cells.Cells are the very small units that make up all――(51)things,including the human body.There are billions of cells――(52)each person’s body.Cancer happens when cells that are not normal...
cancer cells, called "HeLa" after the first two letters of her first and last name, areimmortal, continuing to divide when most cells would die. This ability to survive through endless generations of cells is what makes them invaluable for scientists conducting experiments on human cells. ...
In some cancers, tests may be conducted to see which kind of cell may be involved, as in breast cancer, where surgeons look for cells with estrogen receptors to determine which type of treatment would be most appropriate for the patient's condition. If a doctor suspects that a patient has...
Stem cells share a number of features with cancer cells – both are able to self-renew and double without limit. One theory about cancer holds that the disease most often originates not from terminally differentiated cells but from one of the small number of stem cells in the relevant tissues...

(a) A cancer is characterised by uncontrolled growth and division of certain body cells leading to formation of a tumour. (b) A cancer cell differs from the normal cells in following characters: (i) Grow and divide in an uncontrolled manner. (ii) S
