About Cancer

"Cancer" is a ballad by American rock band My Chemical Romance. It is the eighth track from the group's third studio album The Black Parade. The song was released on October 23, 2006. The original version of the song is written in the key of E major with a common time tempo of 70 beats per minute. The vocals span from E3 to A4 in the song.

A four bar bridge passage prior to the final chorus includes a transposed quotation from the 1958 Buddy Holly hit Raining in My Heart. Its chord progression (featuring a characteristic rising chromatic figure) is highly reminiscent of that from the verse of Raining in My Heart whilst the vocal line closely matches the rhythmic pattern and pitch content of the Bryant and Bryant-penned song. The entire song was written in 8 minutes.
