What do you need help with today?
Start here. We’ll guide you to information and support for your situation.
If something feels urgent right now
Call your cancer care team straight away if any of these start. Most teams have a 24-hour number — it is on your appointment paperwork, and they would far rather hear from you early. If someone cannot breathe, is unresponsive, or you think this is a life-threatening emergency, call 911 or go to the nearest emergency room.
- A fever of 100.4°F (38°C) or higher during treatment — especially chemotherapy — even if you feel okay otherwise
- Signs of infection: shaking chills, redness or swelling around a wound or catheter, or new pain when urinating
- Bleeding that will not stop, or bruising that appears suddenly and spreads
- Severe shortness of breath or new trouble breathing
- Chest pain or pressure
This is not a complete list, and it is not medical advice. Anything that worries you is reason enough to call — you do not need to justify it.
Find information for your situation

Common questions
Answers to the questions we hear most often.
How do I understand my diagnosis?
Start with the pathology report and the words your doctor used. Our Just Diagnosed hub walks through what a diagnosis means, the terms you'll hear, and the questions worth asking at your next appointment.
Just diagnosed? Start here →What are my treatment options?
Treatment depends on the cancer type, its stage, biomarkers, and your own priorities. Our treatment guides explain how surgery, radiation, chemotherapy, immunotherapy, targeted therapy, and hormone therapy work — and what to ask about each.
Explore treatment guides →How do I manage side effects?
Most side effects can be eased, and some need a same-day call to your care team. The Side Effects Explorer shows what's common for each treatment, what helps, and the warning signs that shouldn't wait.
Open the Side Effects Explorer →How can I pay for treatment?
Financial help exists — copay foundations, hospital assistance programs, travel and lodging support, and insurance appeals. Our costs and practical help guides explain where to start, and the Financial Help Finder lists real assistance programs.
Find financial help →How can I support someone with cancer?
Show up, ask what would actually help, and take on specific tasks. Our caregiver hub covers what to say, everyday care, and how to look after yourself while you're helping someone else.

Every question here is one a real person searched for. Each answer is short, sourced, and honest about what varies from person to person.
