Answer 1

31. Ewing's sarcoma is a very rare type of cancerous tumor that grows in your bones or the soft tissue around your bones, such as cartilage or the nerves.

Nuclear medicine technologists prepare and administer small amounts of radioactive substances called radiopharmaceuticals, as well as other medications, to patients for diagnosis and treatments.

The treatment of Ewing's Sarcoma consists of chemotherapy , radiation and surgery . Inbetween chemo physicians prescribe for CECT ,PET CT etc to know the status of the patients disease condition whether the disease in partial remission or complete remission ,is there any new development of mass etc. In this way nuclear medicine uses nuclear medicine for assessment purpose for Basilone comparison with future reports etc .

32. The radiation one typically encounters is one of four types: alpha radiation, beta radiation, gamma radiation, and x radiation. Gamma rays are often considered the most dangerous type of radiation to living matter. Examples are X -ray , ultrasound ,CT scan , MRI scan , whole body PET etc .

33. Two examples of malignant tumor are :-

- Skin cancer

- Ovarian cancer

34. Traveler's diarrhoea is caused by enterotoxigenic Ecoli. Beacause traveler's diarrhea tends to resolve itself, you may get better without any treatment.
