Just diagnosed with breast cancer — what happens next?

You may have just been told you have breast cancer, or you may be waiting after an abnormal test. Most people leave that appointment without a plan for the next few weeks.

This page is for invasive breast cancer, which means the cancer has grown beyond the duct or lobule where it started, usually after a triple assessment and a biopsy. If the result is DCIS (ductal carcinoma in situ), use the DCIS guide. If you were recalled from screening and have not had a biopsy yet, use the screening page.

How long until treatment actually starts?

How the 28-day, 31-day and 62-day NHS clocks are counted, and what to do if a wait slips, is explained in NHS cancer waiting times and urgent breast referrals.

The typical timeline from diagnosis to first treatment in the UK is below. The rows count days from different starting points, so the second column says which clock each row uses.

The wait covers the scans, the multidisciplinary team (MDT) meeting, and the planning appointments. Starting treatment before those results are in can mean the plan has to change later.

That said, the wait is hard. Two things that help: scheduling-related anxiety is best addressed by the breast care nurse team. They are the people who can give you a realistic timeline for your specific scans and appointments. Cancer-related anxiety is best addressed by talking: to family, to a counsellor, to the breast care nurse, to one of the charity helplines. Both are normal; both have practical answers.

If you are reading this on the morning after a diagnosis and want to talk through a private route, phone Sarah or Nadiya, Dr Tsang-Wright’s PAs, on 07785 274 744, email [email protected], or use the contact form. Same-week appointments are usually available.

What “invasive breast cancer” means

The biopsy told the pathologist that breast cancer cells are present. Invasive means the cancer has grown beyond the duct or lobule where it started. The type is most often invasive ductal carcinoma, also called no special type (NST), or invasive lobular carcinoma.

What you do not yet know, and what the next few weeks are designed to find out, is:

• The stage of the cancer: how big it is, whether it has reached the lymph nodes under the arm, and whether there is any sign it has spread further.
• The biology of the cancer: hormone-receptor status (oestrogen, progesterone), HER2 status, and the grade: three pieces of information that drive almost every treatment decision.
• The treatment plan: surgery first, or chemotherapy first; lumpectomy or mastectomy; whether radiotherapy is needed; what hormone therapy looks like over the years afterwards.

These are the questions of the next four to eight weeks. The pathway is built to answer them in order, then to start treatment with the best information available.

The first 48 hours

Most patients are told the result at a clinic appointment about 1 to 2 weeks after the biopsy. The appointment itself is usually 30 to 60 minutes. A senior consultant gives the diagnosis, a breast care nurse joins the conversation, and at the end you are given written information, a contact number for the breast care nurse team, and a follow-up plan.

The first 48 hours are mostly about absorbing the news rather than acting on it. A few practical things help:

• Tell one or two close people first, not a wide circle. You can tell more people later, when you have a clearer picture yourself.
• Don’t make irreversible decisions in the first 48 hours. There is no operation that has to happen tomorrow. The pathway is built around getting the right information first.
• Write down your questions as they come up, even the ones that feel basic. Take the list to the next appointment. The team is used to long question lists. They expect them.
• Use the breast care nurse number. You can ask what a word means, and you can say you cannot sleep or that you are worried about telling your children. The number is on the discharge information.

The breast cancer charities, Breast Cancer Now and Macmillan in particular, have helplines staffed by trained nurses for exactly this moment. Calling them is not a waste of their time; that is what they are for.

Staging tests in the next 1 to 3 weeks

Before treatment can be planned, the team needs to know the stage of the cancer. This usually involves some combination of:

Imaging the breast more thoroughly

A diagnostic mammogram, ultrasound, and sometimes MRI will be repeated to map the cancer in detail. That includes its precise size, whether there are additional smaller cancers in the same breast that weren’t seen initially, and the appearance of the other breast. MRI is particularly useful for invasive lobular carcinoma, which can be hard to size on mammography alone.

Imaging the rest of the body

For early-stage cancers, blood tests and a chest X-ray are often sufficient. For larger cancers, cancers that have already shown signs of nodal involvement, or cancers with worrying biology, more thorough staging is done. That is typically a CT scan of chest, abdomen, and pelvis plus a bone scan (sometimes combined as a PET-CT). This is to look for any sign of spread (metastasis); the great majority of these scans are clear.

The waiting time for these scans varies by hospital and pathway. NHS staging is typically completed within 2 to 3 weeks of the diagnosis appointment; private staging is usually within a week. The wait between the scans being done and the results being discussed is often the hardest part of the pathway: short, but anxious.

Lymph node assessment

In many cases the lymph nodes under the arm have already been imaged at the time of the original biopsy (axillary ultrasound, sometimes with a needle biopsy of any abnormal node). If they look normal, the formal nodal staging is done at the time of surgery via sentinel lymph node biopsy. If the imaging or biopsy showed obvious nodal disease, the surgical plan changes accordingly.

The biology report

Alongside the staging investigations, the pathologist works on the biology of the cancer:

• Oestrogen receptor (ER) and progesterone receptor (PR): see the oestrogen receptor glossary entry. Most invasive breast cancers in the UK are ER-positive, which means hormone therapy will be part of the treatment.
• HER2 status: see the HER2 glossary entry. HER2-positive cancers have effective targeted therapies.
• Grade: how aggressive the cells look under the microscope. See grade and stage for what the numbers mean.

By the end of the staging period, a complete picture is in place: the size, the nodal status, the spread (or absence of spread), and the biology. This is what the multidisciplinary team uses to plan treatment.

The MDT meeting and the treatment-planning conversation

Every breast cancer case in modern UK practice, NHS or private, is reviewed at a multidisciplinary team meeting before treatment is confirmed. The MDT brings together the breast surgeon, oncologist (medical and clinical), radiologist, pathologist, breast care nurse, and (where reconstruction is part of the picture) the plastic surgeon. They review the imaging, the pathology, and the staging together and agree the treatment recommendation.

Within a few days of the MDT, you will have a treatment-planning appointment, usually with your breast surgeon and the breast care nurse, where the recommendation is explained. The questions at this appointment typically include:

“Do I need chemotherapy, and when?”

Some cancers need chemotherapy before surgery (called neoadjuvant chemotherapy); others need it after (adjuvant); others not at all. The decision is driven by the cancer’s biology and stage. If chemotherapy is indicated and is planned before surgery, an appointment with a medical oncologist follows promptly. See the Cancer Research UK page on chemotherapy decisions for an overview. Or use the conversation with your team to walk through your specific picture.

“What kind of surgery?”

The two main paths are breast-conserving surgery (lumpectomy) with radiotherapy afterwards, or mastectomy with or without reconstruction. Both have equivalent long-term survival when each is the right choice for the cancer in question. The factors that drive the decision are the size and position of the cancer, the biology, the patient’s preference, and what reconstructive options are realistic. See Mastectomy or lumpectomy for the longer discussion.

“If mastectomy, what about reconstruction?”

Reconstruction is a major decision in its own right. It can be done at the same operation (immediate) or later (delayed). The options are implant-based, autologous (using the patient’s own tissue), or a deliberate flat-closure result. See Choosing reconstruction and Breast reconstruction. The reconstruction operations are described on their own pages.

“What about radiotherapy?”

Radiotherapy is standard after lumpectomy, and for some patients after mastectomy. For most patients in the UK it is now a daily outpatient treatment over 1 week (5 sessions). Some patients have a 3-week (15-session) schedule, particularly where the nodes or reconstruction change the plan. Treatment usually starts several weeks after the surgery has healed. The clinical oncologist will discuss the specifics at a separate appointment.

“What about hormone therapy?”

For ER-positive cancers (the majority), an oral hormone-blocking medication, tamoxifen or an aromatase inhibitor, is taken for 5 to 10 years after the surgery and other initial treatments. This is one of the most effective parts of breast cancer treatment in reducing recurrence risk; the conversation about which medication and for how long is with the medical oncologist.

“What about targeted therapy?”

If the cancer is HER2-positive, targeted antibody treatment (most commonly trastuzumab) is added to the plan, usually for a year. Some patients receive it as part of chemotherapy; others as a stand-alone infusion course. See the HER2 glossary entry.

These conversations spread across two or three appointments rather than one. Most patients leave the first treatment-planning appointment with the broad shape of the plan and the specifics filled in over the following 1 to 2 weeks as the oncology appointments happen.

Things you can do in the waiting period

The 4 to 6 weeks between diagnosis and the start of treatment are useful for:

• Sort practical plans. Check insurance, time off work, childcare or care for older relatives, and travel you need to move.
• Getting fit: patients who arrive at surgery in better physical shape recover faster. Walking 30 minutes a day, eating well, and sleeping properly are the three things to prioritise. If you smoke, this is the right time to stop, particularly for any patient considering autologous reconstruction. Help with stopping is available through the GP or the breast care nurse.
• Asking questions you didn’t know you had: write them down as they occur. The MDT-planning appointment, the oncologist appointments, and the surgical pre-assessment are all chances to ask. There is no question too basic, and “I don’t know what to ask” is a perfectly fine sentence to start an appointment with.
• Getting a second opinion if you want one. A second opinion at this point is normal, particularly when there is a difficult choice between treatment routes. See the second opinion service for what is involved.
• Setting up support: peer-support groups, online communities (Breast Cancer Now’s Forum, Macmillan’s Online Community), and individual counselling all have a role. The breast care nurse can suggest local options.

What the next 6 to 12 months typically look like

The treatment timeline depends heavily on the specific plan, but a common pattern is:

• Week 0: diagnosis confirmed.
• Weeks 1 to 4: staging investigations and MDT review.
• Weeks 4 to 6: surgery (or first cycle of neoadjuvant chemotherapy if that is the path).
• Months 2 to 5: radiotherapy if indicated (typically 1 week, or 3 weeks in selected cases); chemotherapy if indicated (typically 4 to 6 months including the targeted antibody phase).
• Months 4 to 12: recovery, hormone therapy starts, reconstruction (if delayed), and adjuvant treatments continue. By the 12-month mark most patients are back to a full life, with hormone therapy continuing in the background for years afterwards.

This is one shape; many patients have a different sequence. The team will give you a pathway map at the planning appointment that lays out your specific timeline.

What helps in the early weeks

Some things patients consistently say helped:

• One person to come to all the appointments: usually a partner, sibling, or friend. Two people remember conversations better than one. They also catch the questions you forget to ask.
• A notebook for the appointments: written questions in, written answers out. Digital is fine; paper is fine.
• Being honest with the team about what you do and don’t understand. The job of the breast care nurse and surgeon is to make sure you understand what is being decided. Asking them to explain something a third time is reasonable.
• Saying yes to the breast care nurse phone calls even when you feel fine. The check-in calls catch problems early; the nurse is a useful person to have on your side.
• Tell other people when you are ready. You do not have to tell family, friends, and colleagues all at once.

What you do not have to do

A few common pressures patients describe that are not actually requirements:

• You do not have to make a treatment decision in the first appointment. The pathway is designed for thinking time. If you need a second appointment to weigh up surgery options, ask for it.
• You do not have to read all of the medical literature: Breast Cancer Now, Cancer Research UK, and Macmillan have patient-grade information that is more useful than searching academic papers in the early weeks.
• You do not have to be brave. Brave is a word other people use. It is not a medical requirement.
• You do not have to have a positive attitude. A positive attitude does not change the outcome. The outcome depends on the cancer and the treatment.
• You do not have to know yet what kind of patient you want to be in the months ahead. That settles itself over the first few weeks. Most patients find a routine, a tone, and a circle of support that works for them, but not on day one.

How Breastory fits in

For patients seen in the practice, privately or transferring from an NHS pathway, I am the named consultant from diagnosis through surgery and the long-term follow-up. Sarah or Nadiya, my PAs, book appointments and deal with the hospitals (Chelsea, Harley Street, Buckinghamshire). The breast care nurse team works alongside the surgical practice and is contactable directly.

If you are on an NHS pathway and reading this for context, the same information applies. Your team will deliver the same standard of care, the same MDT process, and the same biology-driven treatment decisions. See the NHS or private comparison if you are weighing whether to move between routes.
