A patient has a tumour in a bone. Receptor Q helps cells continue growing.
Doctors are considering ordinary chemotherapy or a monoclonal antibody treatment developed for receptor Q.
Tests on cells from the patient gave these results:
| Cell type | Number with receptor Q | Number without receptor Q |
|---|---|---|
| Tumour cells | 130 | 70 |
| Healthy cells | 0 | 200 |
Compare the likely effects of the two treatments. Explain how the monoclonal antibody could slow the growth of the tumour and evaluate which treatment would be the better choice for this patient.
