Answer:
the best advice would be to talk to a doctor as soon as he can
Step-by-step explanation:
Based on the situation being described, the best advice would be to talk to a doctor as soon as he can. This is because this pimple might not be anything or maybe basal cell carcinoma (skin cancer) since this type of cancer usually appears on the individual's head or neck and can resemble a pimple or growth. Therefore, it can be very easy to mistake it for a regular pimple and ignore it when it may be more serious and need to be taken care of by a doctor.
