Model answer
Written by UPSC Answer Check against this question's marking rubric, to the expected length. UPSC does not publish answers for Mains — this is one way to score well, not an official key.
Rising Caesarean section rates and oral premalignant lesions need clinical, institutional and nutritional responses.
Maternal care. Globally and in India, Caesarean section rates have risen due to medical and non-medical factors. Medical indications include breech presentation, placenta previa, fetal distress, obstructed labour and previous uterine scar, though many operations are unnecessary. Non-medical drivers include patient/family request, defensive medicine, convenience, private-sector incentives and fee-for-service payment. In India, Janani Suraksha Yojana has increased facility deliveries, but private-sector dominance, urban-rural disparity and weak audit culture allow unnecessary operations, especially in private urban facilities. Robson 10-group classification audits deliveries by parity, presentation, gestational age and mode, identifying groups with high Caesarean rates.
Vaginal birth supports neonatal microbiome colonisation, faster recovery, less blood loss, lower infection/thromboembolic risk and cost. Caesarean section can reduce birth trauma in selected cases and allow planned delivery, but carries haemorrhage, infection, anaesthetic complications, adhesions, longer recovery, higher cost and neonatal respiratory morbidity. Vaginal birth is disadvantageous in obstructed labour, malpresentation or severe fetal compromise. WHO and ICMR-supported Indian studies link high primary Caesarean rates to maternal morbidity without clear neonatal benefit, while low rates may reflect poor skilled-care access.
To reduce unnecessary Caesarean sections, use Robson audit, WHO partograph, midwife-led care for low-risk women, institutional protocols with clear indications, public reporting of facility-level rates, hospital accreditation, and financial disincentives for non-medical operations.
For previous Caesarean section, trial of labour after Caesarean (TOLAC) counselling should be shared decision-making. It is suitable with a previous low transverse incision, no contraindications, and emergency caesarean access. Success rates are 60–80%, uterine rupture risk about 0.5% in low-risk women. NICE-style guidance adapted to India should explain benefits, risks, scar type, interval, labour progress, induction timing, continuous monitoring and immediate theatre availability.
Oral cancer. WHO 2005 defines leukoplakia as a white plaque of questionable risk after excluding known diseases/disorders not associated with increased cancer risk. It is significant because it may show hyperplasia, dysplasia, carcinoma in situ or invasive carcinoma, and is the most common oral potentially malignant disorder; malignant transformation rates vary, often quoted around 1–20%, so biopsy and regular follow-up are essential. Erythroplakia, a red plaque with higher risk, commonly shows dysplasia, carcinoma in situ or invasive carcinoma at biopsy in >80% of cases, with malignant transformation rates about 14–50%. Other premalignant conditions include leukoplakia, erythroplakia, oral submucous fibrosis, lichen planus, syphilitic glossitis, actinic cheilitis and chronic hyperplastic candidiasis. Tobacco, betel quid, alcohol and poor hygiene increase risk.
Oral cavity cancer drains to cervical nodes levels I–V. Submental (Ia) drain floor of mouth, anterior tongue and lower lip; submandibular (Ib) drain anterior mandible, lower lip and floor of mouth; jugulodigastric/upper deep cervical (II) receive posterior tongue, tonsil and oropharynx; lower deep cervical (III–IV) and supraclavicular (V) nodes may be involved in advanced disease.
Protein nutrition. A protein is biologically complete when it supplies all essential amino acids in adequate proportions and is well digested/utilised; assessed by biological value, protein efficiency ratio and net protein utilisation. Animal proteins are usually complete and highly digestible; vegetable proteins are often lower in digestibility and limiting amino acids—cereals low in lysine, pulses low in methionine—so mutual supplementation improves quality. Plant proteins compete with animal proteins on cost, availability, sustainability and preference, though animal proteins remain important for micronutrients and high-quality protein in vulnerable groups, especially children, pregnant women and the elderly.
Proteins are needed for structural tissues, enzymes, hormones, immune antibodies, transport, and energy when carbohydrate/fat are insufficient.
The way forward is integrated public health action: audit maternal care, strengthen oral cancer screening and tobacco control, and improve protein quality through dietary diversification, with community nutrition and tobacco-cessation services, and betel-quid regulation.
What "Discuss" is asking you to do
Lay the issue out from more than one side — how it arose, what is claimed for it, what is held against it, and where it now stands. UPSC attaches discuss to broad topics with several live dimensions, so coverage of the dimensions earns more than the strength of your opinion.
Structure that answers it
Set the issue up → the case as it is made → the case against → the dimension both sides leave out → where the balance now lies
Where marks are lost
Listing facts with no thread between them, or arguing one side throughout and calling it a discussion.
