About CYST
CYST is a small sac or pouch in the body that holds fluid or other material; its plural is CYSTS. It has no A, E, I, O or U, and uses a C, a Y, an S and a T, worth 9 points together. It is a familiar medical word, so it is a safe play when your rack is low on vowels.

CYST scores 9 points
Before any bonus squares: C 3 + Y 4 + S 1 + T 1 = 9. On a double-word square that's 18, on a triple-word 27, and every letter bonus under one of these tiles is applied first.
Example: CYST as the first play
Later in the game, put the Y on a 3L square and CYST is worth 17 before any word bonus.
