Chemotherapy and HER2 treatment Overview

Figure 9

Chemotherapy and the

cell cycle

A cell goes through many

changes to divide into two cells.

Science has grouped these

changes into 7 main phases.

There may be another phase of

rest, too. Some chemotherapy

drugs work in any phase. Other

chemotherapy drugs work in one

or two growth phases.

Chemotherapy may work in some or all phases of cell division.

HER2 antibodies

Antibodies are Y-shaped

proteins that are made by your

body to help fight illness. HER2

antibodies are made in the lab.

They attach to the HER2 on

the outside of the cell, which

prevents growth signals from

starting.
