Which is NOT true about blood cancers They can cause death b

Which is NOT true about blood cancers? They can cause death by impairing the function of the immune system. They can reduce availability of oxygen to the body. All types cause tumors. They can cause hemorrhaging. More than 40% of cancer patients die of_____ rather than the cancer itself malnutrition obstruction to the airways. loss of liver function brain contusions Tumors that lack ____via ___ are limited in how big they can grow. oxygen, vasculogenesis blood supply, angiogenesis blood supply, lymphocytes VEGF, carcinogenesis In which of the following cells would it be beneficial to turn off production of telomerase? Developing embryo cells brain cells metastatic cancer cells skin cells Mutations in tumor suppressor genes on both copies of a cell\'s chromosome pair is like releasing the brakes on cell growth and division. True False

Solution

1. C. All types cause tumors.

Blood cancer is categorized into many types, such as leukemia, myeloma, and lymphoma which present different characteristics features. All type of blood cancers do not cause tumors.

2. A. Malnutrition.

Due to the chemotherapy and other regimes of medicines prescribed to cancer patients, most of them suffer from digestive disorders. As a result of which it is estimated that worldwide, nearly 40% of the cancer patients die of malnutrition.

3. B. Blood supply, angiogenesis

Angiogenesis is the physiological process by which new blood vessels are supplied to the cancerous cells, which cause them to grow bigger in size and produce tumors. In those tumors, where the blood supply is lacking because of lack of angiogenesis, will not grow big in size.

4. C. Metastatic cancer cells.

Telomerase is an enzyme which lengthens the telomeric portions of the chromosomes so that they do not shorten after each round of replication. Hence this enzyme is responsible for increasing the longevity of the cells. It would be beneficial to turn off the telomerase in metastatic cancer cells so that they are not able to progress.

5. A. True

Tumor suppressor gene products in our body prevent the formation of the tumor by regulating cell growth and division. But when both the copies of the gene is mutated, then this control is lost.
