Abnormal bleeding
Bleeding between periods, after intercourse, or any bleeding after menopause.
Cancers of the female reproductive system — cervical, endometrial, ovarian, vaginal and vulvar — each behave differently and are treated differently. AARO offers fellowship-trained gynaecological radiation oncology, including image-guided brachytherapy, with the choice of a female specialist.
Gynaecological cancers arise in the organs of the female reproductive system, categorised by organ and cell type. Ovarian cancers mostly develop from the epithelial cells covering the ovary (85–90%), with rarer stromal and germ cell tumours. Endometrial cancer — cancer of the womb's inner lining — is mostly adenocarcinoma.
Cervical cancer is the tenth most common cancer in Singaporean women. Around 90% are squamous cell carcinomas beginning in the cervix's transformation zone, where pre-cancerous changes accumulate gradually — changes a Pap smear can detect years before cancer develops. Adenocarcinomas and mixed types make up the rest.
Vaginal and vulvar cancers are rarer, mostly squamous cell carcinomas, and can likewise be preceded by detectable pre-cancerous change. Across all five organs, the exact diagnosis — organ, cell type, stage — determines the treatment plan.
Abnormal bleeding is the signature warning sign across gynaecological cancers — and it should never be dismissed.
Bleeding between periods, after intercourse, or any bleeding after menopause.
Persistent watery, bloody or foul-smelling discharge.
Persistent pelvic pain, pressure, or pain during intercourse.
Persistent bloating or feeling full quickly — classic (and easily missed) ovarian symptoms.
New urgency, frequency or bowel changes that persist.
Itching, burning, a lump or skin change on the vulva that doesn't resolve.
From screening tests that catch pre-cancer to precise staging — diagnosis is where the treatment plan takes shape.
Pap smears and HPV testing detect cervical pre-cancer years early; pelvic examination assesses symptoms.
Ultrasound, then MRI, maps the tumour's size and local extent — critical for radiotherapy planning.
Tissue from the cervix, endometrium or vulva confirms the diagnosis and type.
CT and PET-CT complete the stage, assessing lymph nodes and distant sites.
Several gynaecological cancers have identifiable — and partly preventable — risk factors:
Persistent human papillomavirus infection causes most cervical, vaginal and vulvar cancers — HPV vaccination prevents it.
Most cervical cancers occur in women who haven't had regular Pap/HPV screening.
Unopposed oestrogen exposure and obesity raise endometrial cancer risk.
BRCA mutations and Lynch syndrome raise ovarian and endometrial cancer risk.
Risk of most gynaecological cancers rises after menopause.
Smoking raises cervical and vulvar cancer risk.
Radiotherapy is central to gynaecological cancer treatment — and brachytherapy, delivered from within, is what makes cervical cancer curable at high doses the body could never tolerate externally.
Internal radiation for cervix and endometrium — fellowship-trained expertise, shaping dose from inside the tumour itself.
Intensity-modulated external radiation keeps bowel and bladder dose low across every pelvic course.
Radiation with concurrent chemotherapy — the curative standard for locally advanced cervical cancer.
Dr Michelle Tseng sub-specialised in women's cancers so women have the choice of a female radiation oncologist.
Every plan at AARO goes through detailed contouring, dose simulation, and independent physics review before a single beam is delivered. We do this so the radiation hits exactly the tissue that needs it — and avoids the healthy tissue around it.
Our medical physicists and radiation therapists collaborate on each plan — contouring tumour and organs-at-risk, simulating dose distribution, and independently checking every parameter before delivery.
Imaging before each fraction confirms the target's position to the millimetre — so tight margins stay safe, and healthy tissue stays out of the high-dose region.
Each treatment session takes 15–30 minutes. You'll lie on a precision treatment couch beneath the linear accelerator. Positioning lasers and daily imaging align you to within a millimetre of the planned position.
You won't feel the radiation as it's delivered. There's no anaesthesia, no recovery time, and no overnight stay. Most patients drive themselves home after the session and return to normal activities the same day.
Gynaecological radiation at AARO is delivered by two fellowship-trained brachytherapy specialists — including the choice of a female consultant.
Book a 45–60 minute specialist consultation. We'll review your imaging and pathology, explain the options that apply to your case, and answer your questions.
