How is cancer treated in a technique called teletherapy?

Teletherapy is the external radiotherapy that uses an external source of radiation to kill the tumor cells.

Explanation:

Teletherapy is the external radiotherapy that uses an external source of radiation to deliver the radiations such as gamma rays or high energy x rays to kill the tumor cells. Teletherapy is a noninvasive treatment method of cancer and uses the ionizing radiations to target the cancer cells. To minimize the harmful effects on healthy tissues, radiations are given at different angles.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
