Breast cancer is a disease in which abnormal cells grow uncontrollably in the breast tissue. It is one of the most common cancers and can affect both women and men. Early detection, awareness, and advanced treatments have improved survival and recovery rates.

Overview of the Condition

What is breast cancer?

Breast cancer is a disease in which abnormal cells grow uncontrollably in the breast tissue. It is one of the most common cancers and can affect both women and men. Early detection, awareness, and advanced treatments have improved survival and recovery rates.

Why is it important?

Early detection of breast cancer is important because it increases the chances of successful treatment, prevents the cancer from spreading, and helps improve survival and recovery outcomes. Statistics estimate that approximately 29% women may develop breast cancer.

Who is commonly affected?

Causes / Why It Happens

Breast cancer occurs when cells in the breast develop DNA changes and start growing uncontrollably, forming a tumor that may spread to other parts of the body. It is influenced by a combination of genetic, hormonal, lifestyle, and environmental factors.

Risk factors

Common risk factors include:

  • Family or personal history of breast cancer
  • Increasing age
  • Hormonal changes and early periods/late menopause
  • Obesity and lack of physical activity
  • Alcohol consumption and smoking
  • Dense breast tissue
  • Late pregnancy or never being pregnant
  • Genetic mutations such as BRCA1 and BRCA2
  • Previous radiation exposure
  • Long-term hormone replacement therapy

Symptoms

Common symptoms include:

  • Lump or thickening in the breast
  • Change in breast size or shape
  • Nipple turning inward
  • Redness or changes in breast skin color
  • Dimpling or orange peel-like skin
  • Peeling or scaling of breast skin
  • Pain or unusual changes in the breast or nipple area
  • New lump or swelling
  • Blood in urine or stool
  • Coughing up blood

Treatment Options (Before Procedure)

  • Chemotherapy: Uses medicines to destroy cancer cells
  • Radiation therapy: Uses high-energy rays to kill cancer cells
  • Immunotherapy: Helps the body’s immune system fight cancer
  • Targeted therapy: Targets specific cancer cells while reducing damage to normal cells
  • Sentinel lymph node biopsy (SLNB): SLNB is a procedure used to check whether cancer has spread to the first nearby lymph node, helping doctors determine the stage of cancer and plan treatment

Procedure Overview and Preparation

What is SLNB and why is it done?

SLNB: It is a procedure used to check whether cancer has spread to nearby lymph nodes. During the procedure, a dye or tracer is injected near the tumor to identify the first lymph node (sentinel node), which is then removed and tested for cancer cells to help guide treatment decisions.

Procedure Overview

Step-by-step

  • A blue dye or radioactive tracer is injected near the tumor
  • The surgeon identifies the sentinel lymph node using the dye or tracer
  • A small cut is made to remove the lymph node
  • The node is tested for cancer cells in the laboratory
  • Additional lymph nodes may be removed if cancer is detected
  • The procedure is usually done along with tumor removal surgery

Time required

  • 1-2 hours

Risks, Benefits and Hospital Stay

Risks and Complications

  • In some cases, the surgeon may need to switch to open surgery during the procedure
  • Possible risks include bleeding, infection, blood clots, or anesthesia-related complications
  • Some procedures may take slightly longer due to robotic system setup

Benefits and Expected Outcomes

  • Helps determine whether cancer has spread to nearby lymph nodes
  • Assists doctors in staging the cancer and planning treatment
  • May help avoid extensive lymph node removal surgery
  • Reduces the risk of complications such as arm swelling and pain

Duration of Hospital Stay

  • Usually same-day discharge or 1-day hospital stay

Recovery, Lifestyle and Follow-up

Recovery and Aftercare

  • Patients are encouraged to walk early, maintain hydration, and follow wound-care instructions

Recovery Timeline

  • 1-2 weeks

Lifestyle and Prevention

Long-term care

  • Maintain healthy body weight
  • Exercise regularly
  • Avoid smoking and excessive alcohol
  • Perform regular breast self-examination
  • Regular follow-up appointments
  • Mammograms and imaging as advised
  • Monitoring for recurrence

When to Contact a Doctor

  • Seek medical attention if you experience:
  • Fever
  • Excessive swelling or redness
  • Severe pain
  • Bleeding or discharge from the wound
  • Arm swelling

Follow-up

Regular follow-up is important to monitor healing and detect recurrence early. Follow-up may include:

  • Physical examination
  • Breast imaging
  • Blood tests

Myths and Facts

Myth 1: SLNB removes all lymph nodes

Fact: SLNB removes only the first few lymph nodes most likely to contain cancer cells.

Myth 2: If one lymph node is positive cancer has spread everywhere.

Fact: A positive sentinel node means cancer may have spread nearby, and further evaluation helps decide treatment.

Myth 3: SLNB is a major surgery with long recovery.

Fact: SLNB is a minimally invasive procedure with smaller cuts and faster recovery than full lymph node removal.

Myth 4: All breast cancer patients need complete lymph node removal

Fact: Many patients only need SLNB, which lowers the risk of complications like arm swelling (lymphedema).

FAQs

What is SLNB used for?

SLNB is used to check whether cancer has spread to nearby lymph nodes.

Which cancers commonly use SLNB?

SLNB is most commonly used for breast cancer and melanoma.

Is SLNB painful?

The procedure is usually done under anesthesia, so patients feel little or no pain during surgery.

What are the benefits of SLNB?

SLNB helps detect cancer spread early while reducing unnecessary lymph node removal and lowering the risk of lymphedema.
