Yes, you're absolutely right.
A month is a reasonable time frame. When we strongly suspect a patient has cancer, we have to speed up the process as much as possible. The problem is that we can't confirm the patient has cancer until they undergo medical imaging. Most patients who fall into the P3 category will have to wait three to six months, instead of one month. That gives the disease time to progress to another stage, so instead of performing curative surgery, doctors can merely treat patients with radiation and chemotherapy. The mortality risk is inevitable.
