Anointing of Sick question

Hello all im (26m) and was wondering if i can receive the Sacrament of Anointing of the Sick before i start chemo in the next 2 weeks or if it was reserved for more serious/ life threatening illnesses.

If so, what am i to expect? Does the priest do most of the talking or are there lines/prayers i have to recite as well?

Thank you and God Bless you all❤️
