This document is an excerpt from "Understanding Breast Cancer," a patient guide published by Cancer Council Australia in September 2024. Designed to support individuals diagnosed with breast cancer, as well as their families and friends, the booklet provides a thorough overview of the disease, covering the biology of cancer, the anatomy of the breast, and risk factors. It details the diagnostic process, including imaging tests like mammograms and ultrasounds, biopsies, and the staging/grading of cancer. The text explains complex pathology results such as hormone receptor status, HER2 status, and triple-negative breast cancer, offering insight into how these factors influence treatment decisions. Furthermore, it outlines treatment options ranging from breast-conserving surgery and mastectomy to reconstruction, while emphasizing the importance of multidisciplinary care, emotional support, and making informed decisions through resources like second opinions and clinical trials.
2. Topics, Headings, and Key Points
What is Cancer?
Definition: A disease where abnormal cells grow uncontrollably.
Malignant vs. Benign: Malignant tumors can spread to other parts of the body (metastasis); benign tumors do not.
Primary vs. Secondary: The original cancer is primary; if it spreads, the new tumors are secondary or metastases.
The Breasts & Anatomy
Structure: Made up of lobes (milk-producing sections), lobules (glands), ducts (tubes carrying milk), and fatty/fibrous tissue.
Lymphatic System: A network of vessels and nodes (glands). The first place breast cancer usually spreads is to the lymph nodes in the armpit (axilla).
Key Facts & Risk Factors
Prevalence: About 20,700 people diagnosed annually in Australia; 1 in 8 women by age 85.
Risk Factors: Being female, aging, family history (gene mutations like BRCA1/2), lifestyle factors (alcohol, weight, smoking), and hormonal factors.
Symptoms: Lumps, changes in size/shape, skin dimpling, nipple changes (inversion, discharge), or pain.
Diagnosis & Testing
Triple Test: Physical examination, imaging (mammogram, ultrasound, MRI), and biopsy.
Biopsy Types: Fine needle aspiration (FNA), core biopsy, vacuum-assisted, or surgical biopsy.
Staging: The TNM system (Tumour size, Node involvement, Metastasis).
Early (Stage 1-2): Contained in breast/armpit.
Locally Advanced (Stage 3): Larger or spread to skin/chest muscle.
Metastatic (Stage 4): Spread to distant body parts.
Grading: How fast the cancer is growing (Grade 1 = slow, Grade 3 = fast).
Understanding Tumour Biology
Hormone Receptors: ER+ (Oestrogen) and PR+ (Progesterone). These cancers respond to hormone therapy.
HER2 Status: A protein that helps cancer grow. HER2+ cancers respond to targeted therapies.
Triple Negative: Lacks ER, PR, and HER2. Treated mainly with chemotherapy and immunotherapy.
Treatment Planning
Multidisciplinary Team (MDT): A group of specialists (surgeons, oncologists, nurses) who plan care together.
Decision Making: Involves understanding prognosis, considering second opinions, and discussing clinical trials.
Surgical Treatments
Breast-Conserving Surgery (Lumpectomy): Removes the tumor and some healthy tissue; usually followed by radiation.
Mastectomy: Removes the whole breast. May be single or bilateral (both).
Reconstruction: Creating a new breast shape using implants or own tissue, done at the same time or later.
Axillary Surgery: Removal of lymph nodes to check for cancer spread.
3. Easy Explanation (Plain English)
What is Breast Cancer?
Imagine your body is like a busy city with buildings (cells) that are constantly being built and torn down. Usually, this happens in an orderly way. Breast cancer happens when some cells stop following the rules and start building out of control, forming a lump (tumor). These "bad cells" can break away and travel to other parts of the city (body), which doctors call metastasis.
How do doctors find it?
Doctors use three main methods to check for breast cancer:
Feeling: The doctor physically checks the breasts and armpits for lumps.
Pictures: They use X-rays (mammograms) or soundwaves (ultrasound) to look inside the breast.
Sampling: If they see something suspicious, they take a tiny piece of tissue (a biopsy) to look at under a microscope.
What do the test results mean?
Doctors look for specific "locks" on the cancer cells to decide which medicine (key) will work best:
Hormone Receptors (ER/PR): If the cancer uses hormones to grow, doctors give drugs to block those hormones.
HER2: If the cancer has too much of a specific protein, doctors use targeted drugs to attack it.
Triple Negative: If the cancer has none of these, doctors use strong drugs (chemotherapy) to kill the cells.
What is the treatment?
Surgery: You can either have just the lump removed (keeping the breast) or the whole breast removed. You can also choose to have the breast rebuilt (reconstruction) afterward.
Other Treatments: Sometimes, doctors give medicine before surgery to shrink the tumor (neoadjuvant) so the surgery is easier. Other times, they give medicine after surgery (adjuvant) to kill any leftover cells.

Slide 2: What is Breast Cancer?
The Basics: Abnormal growth of cells in the breast tissue.
Invasive: Cancer has spread from the ducts/lobules into surrounding tissue.
Metastatic (Advanced): Cancer has spread to distant parts of the body (e.g., bones, liver).
Anatomy: Starts in ducts (80%) or lobules.
Slide 3: Risk Factors & Symptoms
Who is at risk?
Primarily women (99% of cases), but men can get it too.
Risk increases with age (especially over 50).
Family history (BRCA1/2 genes) and lifestyle factors (alcohol, weight).
Warning Signs:
New lumps or thickening.
Change in size/shape.
Nipple changes (inversion, discharge, crusting).
Skin dimpling or redness.
Slide 4: Diagnosis Process
Step 1: Imaging
Mammogram: Low-dose X-ray (screening/diagnostic).
Ultrasound: Soundwaves (good for younger/dense breasts).
MRI: For high-risk patients or complex cases.
Step 2: Biopsy
Taking a tissue sample (Core needle, FNA, or Surgical).
Only way to confirm cancer.
Step 3: Staging & Grading
Determining how far it has spread (Stage 1-4) and how fast it grows (Grade 1-3).
Slide 5: Understanding Your Results (Pathology)
Hormone Receptors (ER/PR):
Positive (+): Cancer feeds on hormones. Treatment: Hormone Therapy.
Negative (-): Does not feed on hormones.
HER2 Status:
Positive (+): Too much HER2 protein. Treatment: Targeted Therapy.
Triple Negative:
ER-, PR-, HER2-.
Treatment: Chemotherapy and Immunotherapy.
Slide 6: Treatment Options
Surgery:
Breast-Conserving (Lumpectomy): Remove lump + margin. Usually needs radiation.
Mastectomy: Remove whole breast. Option for immediate reconstruction.
Therapy Sequence:
Neoadjuvant: Treatment before surgery to shrink tumor.
Adjuvant: Treatment after surgery to kill remaining cells.
Other Therapies:
Radiation Therapy, Chemotherapy, Hormone Therapy, Targeted Therapy, Immunotherapy.
