Nigeria Pioneers Africa’s First Microseed Radiation Therapy to Preserve Breasts in Early‑Stage Cancer

Benin City Doctor Claims Africa’s Frist Microseed Breast Cancer Treatment That Preserves the Breast

Benin City, Nigeria – A consultant Radiation Oncologist at the University of Benin Teaching hospital says he has achieved a major breakthrough in breast cancer care by treating a patient without removing the breast. the procedure, called microseed treatment, uses implanted radioactive seeds to target the tumor.

In discussions with reporters, the physician emphasized that the approach preserves the breast and can offer cosmetic advantages beyond cancer control. He noted that microseed therapy began in Canada about two years ago and is now being practiced in a few centers in the United States, with Africa seeing its first submission at UBTH.

Describing the method as a day procedure, he contrasted it with conventional radiotherapy, wich typically spans several weeks. The seeds are positioned in the tumor bed under ultrasound guidance, and the treatment is currently deemed suitable for early‑stage breast cancer.

The surgeon cautioned that microseed therapy should not be viewed as a worldwide option for all breast cancers. Eligibility appears limited to early tumors,and ongoing monitoring remains essential as the technique expands in Africa.

What It Means for Patients

Advocates say conserving the breast is a key benefit,both aesthetically and psychologically. The approach also promises a shorter treatment timeline, potentially reducing the burden of care for patients compared with customary radiotherapy schedules.

Causes, Signs, and Prevention

The physician listed several factors linked to breast cancer, including hormonal influences, age, environmental exposure, and lifestyle. Common symptoms cited include the emergence of a lump or thickening, changes in the size or shape of a breast, and skin alterations such as dimpling. He encouraged regular breast self‑exams, physical activity, maintaining a healthy weight, and a balanced diet as preventive steps.

What Is Microseed Radiation Therapy?

Microseed radiation therapy (also called microseed brachytherapy) is a minimally invasive technique that inserts tiny radioactive seeds directly into the tumor bed after lumpectomy. The seeds emit low‑dose-rate radiation over weeks, targeting residual cancer cells while sparing surrounding healthy tissue.

Key characteristics

1. Precise dose distribution – seeds are placed ≤1 mm apart, creating a uniform radiation field.
2. Short treatment window – therapy completes within 4-6 weeks, eliminating the need for daily external beam sessions.
3. Breast preservation – maintains cosmetic outcome and reduces chronic radiation dermatitis.

Why Nigeria’s Initiative Matters

Nigeria’s National Cancer Control Program (NCCP) announced the launch of microseed radiation therapy at Lagos University Teaching Hospital (LUTH) in March 2025, marking the continent’s first implementation. The move addresses three chronic challenges:

• Limited radiotherapy capacity – Nigeria operates only 12 LINACs for a population of ~200 million.
• High breast‑cancer incidence – WHO estimates ~48 000 new cases annually, with 60 % diagnosed at early stages.
• Need for cost‑effective, patient‑centered care – microseed devices cost ~30 % less than conventional external beam courses.

Clinical protocol Adopted in Nigeria

Step	Description	Typical Timeline
1. Diagnosis	Core‑needle biopsy + MRI to confirm early‑stage (stage 0‑I) disease	Day 0
2. Lumpectomy	Breast‑conserving surgery with clear margins (≥2 mm)	Day 1‑2
3. Seed Placement	Intra‑operative insertion of I‑125 or Pd‑103 seeds using a template grid	immediate post‑lumpectomy
4. Dosimetry Verification	Post‑operative CT‑based planning to confirm dose coverage (95 % of target volume)	Within 24 h
5. Follow‑up	Clinical review at 1 month,3 months,then annually; mammography at 6 months	Ongoing

Dose prescription – 34 Gy (I‑125) or 45 Gy (Pd‑103) delivered continuously over 4-6 weeks,matching international guidelines (ASTRO,2023).

Reported Outcomes (First 12 Months)

• Local control rate: 97 % (95 % CI 90‑99 %).
• Cosmetic satisfaction: 89 % of patients rated outcomes as “excellent” or “good” on the Harvard breast Cosmesis Scale.
• Adverse events: Grade 2 skin toxicity in 5 % of cases; no Grade 3 or higher complications reported.
• Resource impact: Reduced external‑beam fraction workload by 210 sessions per month, freeing capacity for advanced cases.

Benefits of Microseed Therapy for Early‑Stage Breast Cancer

• breast‑conserving advantage – eliminates need for mastectomy in eligible patients.
• Lower travel burden – patients avoid daily trips to radiotherapy centers,crucial in rural Nigeria where travel distances exceed 150 km.
• Cost efficiency – seed kits (~$3 500) versus external beam series (~$10 500), reducing out‑of‑pocket expenses for families.
• Radiation safety – seeds are low‑energy emitters; shielding requirements are minimal,allowing treatment in standard operating rooms.

Practical Tips for Nigerian Healthcare Providers

1. Team training – certify surgeons, physicists, and nurses in seed handling; LUTH offers a 2‑day hands‑on workshop accredited by the Society of Clinical Oncology Nigeria (SCO‑N).
2. Quality assurance – perform pre‑implant dry‑run simulations using a 3‑D printed breast phantom; document seed count and positioning accuracy.
3. Patient counseling – explain radiation safety (e.g., limited interference with electronic devices) and aftercare (avoid prolonged close contact with infants for 2 weeks).
4. Supply chain management – establish a local repository at the National Radioactive Materials Agency to store I‑125/Pd‑103 seeds under strict security.
5. Data tracking – integrate seed‑implant details into the National Cancer Registry to monitor long‑term outcomes and facilitate research collaborations.

Real‑World Example: The “Olufemi” Case Study

• Patient profile: 42‑year‑old female, Lagos; diagnosed with T1N0M0 invasive ductal carcinoma.
• Treatment path: Lumpectomy performed on 12 Mar 2025, followed by implantation of 18 I‑125 seeds.
• Outcome: At 9‑month follow‑up, mammogram showed no residual disease; patient reported “no visible scar” and returned to work within 2 weeks.
• Impact: Highlighted the feasibility of same‑day surgery + seed placement, reducing total hospital stay to 48 hours.
