When Corinne
enters the room, she lies on the table and an uncomfortable, plastic
brace is placed under her neck so that she properly presents herself
to the x-rays. Then her mask is placed and latched down to the
table. At that point, the radiation therapists rapidly and efficiently
busy themselves lining up the table and the machine and Corinne
so the radiation is exactly targeted. Corinne lies with her eyes
and mouth pressed shut by the mask, hearing all of the activity,
but having no idea what is going on. She is nervous. She is afraid
of the radiation thats set to damage her. She is very brave.
Before these
treatments began, complicated physics calculations determined
just the right dose and placement of radiation to
do the job. Since she is scheduled for 18 sessions, each treatment
delivers a 1/18 th fraction of the entire dose. As with chemotherapy,
there is a maximum amount of radiation a person can safely receive.
Radiation doses are computed carefully to avoid unnecessary damage
to tissue and to conserve the patients ability to tolerate
future treatments, if needed.
Over the two
years after Lindas breast cancer first appeared, she had
two additional recurrences of cancer. In her first recurrence,
four nasty brain tumors were aggressively treated with both chemotherapy
and x-ray therapy. She also had a new procedure using the Gamma
Knife, a one-time treatment which shoots scores of tiny radiation
beams from different directions, all crossing on the tumor and
killing it. These treatments, combined, apparently destroyed the
four tumors. But, a year later when a different type of brain
cancer appeared, Linda had reached her limit on chemotherapy and
radiation. The new cancer was terribly aggressive. She could not
be saved. She died.
