A friend has cancer. What can you say that actually helps?

Start with a simple message, offer one specific thing you can do, and let your friend decide what would help. You do not need a perfect speech. Listening, staying in touch and following through on an agreed task are practical places to begin.

This guide brings together advice from Macmillan Cancer Support and Breast Cancer Now, with original message examples you can adapt. It is about friendship and everyday help; your friend’s healthcare team remains the source for treatment advice.

Send something they can answer easily

“Let me know if you need anything” comes from kindness. A clear offer gives your friend something concrete to accept, change or decline.

Try one of these:

• “I’m going to the supermarket on Thursday. Would you like me to pick up anything and leave it by your door?”
• “I’m free on Tuesday afternoon. Would a lift be useful?”
• “Would you like some company this weekend, or would another day suit you better?”
• “Thinking of you. There’s no need to reply to this message.”

Choose an offer you can keep. Give a time if that matters. If the answer is no, accept it warmly.

For the first message after hearing the news, plain words are enough: “I’m sorry you’re going through this. I care about you, and I’m here.”

Let your friend set the conversation

Macmillan’s advice on talking with someone who has cancer emphasises listening and allowing honest feelings. It advises against promises that everything will be fine, pressure to stay positive, or comparisons with other people’s cancer stories.

You might ask, “Would you like to talk about today, or shall I tell you about something completely ordinary?” Then follow their answer. If they want to talk, leave room for them to finish.

If you get the words wrong, a brief apology can help you move on: “I’m sorry. That came out badly. I’m listening.” Your friend should not have to reassure you at length about it.

Turn an offer into a small, reliable plan

Macmillan suggests that friends can help with things such as appointments or company, and that shared support should reflect the person’s wishes. Its guide for family and friends is a useful starting point.

Once an offer is accepted, confirm the details. Here is a simple planning note you can copy:

• The task: A lift to an appointment.
• The details to check: Pickup time, address and whether a return lift is needed.
• Your friend’s preference: Drop-off only, or company inside?
• Who is doing it: One named person.
• If plans change: The best way to let each other know.

The same format works for collecting shopping, walking a dog or an agreed household job. Ask before arranging a group rota. A spreadsheet full of surprises is still a surprise.

For meals, first check what they would like and whether there are dietary instructions or allergies you need to know about. Make the handover straightforward; delivering something need not become a visit.

Keep their news theirs

Breast Cancer Now notes that, with permission, helping to update others can take pressure off someone. Start by agreeing exactly what they want shared, and with whom.

You can ask: “Would it help if I updated the group? If so, what would you like me to say?”

Keep the agreed message as it is. Check before sharing photographs, appointment details or updates on social media. A friend telling you something privately is not the same as giving permission to pass it on.

Offer help within your role

There is a difference between doing an errand and taking on personal or medical care. Macmillan’s practical care guidance explains that the healthcare team can advise as someone’s needs change. Tasks such as helping someone move safely may need professional guidance.

If your friend needs more help than you can provide, say so clearly and kindly. You can offer to help them find the right contact. Being dependable includes being honest about your limits.

Avoid sending treatments, supplements or skincare as a solution to treatment effects. Ask what your friend wants, and leave suitability questions to their clinical team.

Keep ordinary friendship in the picture

Your friend may want to talk about their diagnosis, their favourite television programme, a family irritation or none of these. Breast Cancer Now advises being guided by the individual; some people welcome ordinary conversation as a distraction.

Keep invitations easy to decline or change. For example: “I’m having a quiet coffee on Saturday. You’re welcome if you fancy it, and we can decide on the day.”

Support is available for you, too

Macmillan supports family and friends as well as people with cancer. Its Support Line is 0808 808 00 00. The Breast Cancer Now helpline is 0808 800 6000. Check their websites for current opening hours.

For a useful next step today, choose one message and one realistic offer. Send the message. If the offer is accepted, put the agreed task in your diary.
