(ii) Malignant tumors remain confined to their original location.
(iii) Cancer cells do not exhibit contact inhibition.
(iv) X-rays and UV rays are not potent carcinogens.
(v) Cancer detection is based on biopsy.
Which of the above statements are not correct regarding cancer ?

Read the following five statements (A to E) about cancer and select the option with all correct statements: (A) Cancer cells do show a property called contact inhibition. (B) Cancer is one of the most dreaded diseases of humam beings. (C)Cancer causing viruses called oneogenic viruses have ganes called viral oncogenes. (D) Ionising rediations like X-rays and gamma rays and non-ionizing radiations like UV cause DNA repair and prevent cancer. (E) Cancer detction is based on biopsy and histopathological studies of the tissue.

Read the following statements and select the correct option. Statement 1 : Malignant tumors normally remain confined to their original location, do not spread to other body parts and cause less damage. Statement 2 : Cancer arising from epithelial tissues of internal organs and glands is referred to as sarcoma e.g., breast cancer, cervical cancer etc.

Read the following statements regarding the various techniques used in cancer detection. (i) Cancer detection is based on biopsy and histopathological studies of the tissue, and blood and bone marrow tests for increased cell counts in case of leukaemia. (ii) In biopsy, a piece of the suspected tissue cut into thin sections is stained and examined under microscope by a pathologist. (iii) Techniques like radiography (use of X-rays), CT (computed tomography) and MRI(magnetic resonance imaging) are very useful to detect cancers of the internal organs. (iv) Computed tomography uses strong magnetic fileds and non-ionising radiations to detect physiological changes in living tissues. (v) MRI uses X-rays and ionising radiation to generate a 3-D image of the internal structure of an object. Which of the above statements are incorrect ?
