Palliative care

What it is

Palliative care is specialised care that improves quality of life for people with serious illness; globally, only about 14% who need it receive it. It focuses on preventing and relieving suffering through early identification, assessment, and treatment of pain and other physical, emotional, social, and spiritual problems. Palliative care is not the same as giving up treatment, and it is not limited to the last days of life. It can be started at diagnosis, during active cancer treatment, after treatment, or near the end of life.

The World Health Organization estimates that 56.8 million people need palliative care each year, including 25.7 million in the last year of life. For cancer patients and families, the most important point is that palliative care can be given alongside chemotherapy, radiation, surgery, immunotherapy, or other disease-directed treatment.

Palliative care is usually delivered by a team. Depending on the setting, that team may include doctors, nurses, pharmacists, psychologists, social workers, physiotherapists, counselors, spiritual care providers, and trained volunteers. In India, palliative care may be available in cancer centres, hospitals, hospices, and home-based programmes, but access still varies widely by state and city.

Palliative care	Hospice / end-of-life care
Can begin at any stage of a serious illness	Usually focuses on the final months or weeks of life
Can be given with curative or life-prolonging treatment	Often emphasises comfort when disease-directed treatment is no longer helping or is not wanted
Addresses symptoms, stress, family support, and care planning	Includes these goals, with stronger focus on dying and bereavement support

How it works

Palliative care works by identifying sources of suffering early and treating them in a structured, person-centred way. In cancer, this often means regular review of pain, nausea, vomiting, constipation, breathlessness, fatigue, anxiety, depression, sleep problems, appetite loss, and practical concerns such as finances or caregiver strain.

The team usually starts with a symptom assessment and a discussion of the patient's goals. For one person, the priority may be pain relief so they can continue treatment. For another, it may be staying at home, avoiding repeated hospital visits, or being able to eat, sleep, and talk comfortably with family.

Common parts of palliative care include:

1. Symptom control, including medicines and non-drug measures.
2. Communication about prognosis, treatment choices, and what matters most to the patient.
3. Psychological and social support for patients and caregivers.
4. Advance care planning, including preferences for future treatment and place of care.
5. Coordination across hospital, clinic, and home care.

Pain relief is a major part of palliative care, and opioids such as morphine are considered essential medicines for severe cancer pain by WHO. Palliative care also uses many non-opioid medicines and supportive measures. Good palliative care aims to improve comfort and function while reducing avoidable crises and hospital admissions.

Evidence and uses

Palliative care is used for cancer and many other serious illnesses, including heart failure, chronic lung disease, kidney failure, liver disease, dementia, Parkinson's disease, and advanced infections. In oncology, it is commonly used for symptom burden, treatment side effects, advanced disease, and support with difficult decisions.

Evidence supports palliative care for improving symptom control, communication, and patient and caregiver experience. WHO states that early palliative care can reduce unnecessary hospital admissions and use of health services. Major health systems also recognise that palliative care can be integrated with standard medical treatment rather than replacing it.

In cancer care, palliative care may help with:

• Cancer pain
• Breathlessness
• Nausea and vomiting
• Constipation, especially from opioids or chemotherapy
• Fatigue and weakness
• Anxiety, depression, and fear
• Sleep disturbance
• Family meetings and care planning
• Support near the end of life

Evidence is stronger for some outcomes than others. Symptom relief and better communication are well supported. Effects on survival, healthcare costs, or specific quality-of-life measures can vary by disease, timing, and how the service is delivered. Research in palliative medicine is also harder to conduct than in many other specialties because patients are medically fragile, needs change quickly, and outcomes are not always easy to measure.

For India, palliative care is especially relevant because many patients still reach cancer services with advanced disease or high symptom burden. Access to trained teams, home care, and essential pain medicines remains uneven. This means the benefit of early referral may be large, but actual availability depends on local services.

When to see a clinician

Ask about palliative care if you or your family member has a serious illness and any of the following apply:

• Pain or other symptoms are not well controlled
• Cancer treatment side effects are affecting daily life
• There have been repeated emergency visits or hospital admissions
• You need help understanding treatment choices
• The patient or family feels overwhelmed, anxious, or unsupported
• There are questions about home care, feeding, mobility, or future planning

You do not need to wait until treatment stops. Many patients benefit most when palliative care starts early, especially if symptoms are already affecting sleep, eating, movement, or mood. In cancer centres, you can ask the oncologist directly for a palliative care referral.

Seek urgent medical attention for severe uncontrolled pain, sudden breathlessness, confusion, heavy bleeding, seizures, or inability to take essential medicines or fluids.

Limitations and open questions

Palliative care is strongly recommended by major health organisations, but access is still limited worldwide and in many parts of India. A major barrier is the mistaken belief that palliative care means only terminal care. Other barriers include shortage of trained staff, limited home-based services, and poor access to essential medicines in some settings.

There are also evidence gaps. Studies do not all use the same definitions, timing, or outcome measures, so results can be difficult to compare. Some interventions that seem helpful in practice have limited high-quality trial data. Research is ongoing on the best models for early integration, tele-palliative care, caregiver support, and culturally appropriate care.

Palliative care should be individualised. What helps one patient may not fit another patient's goals, family situation, or stage of illness. If palliative care is offered, it is reasonable to ask what services are actually available, who will coordinate care, whether home support exists, and how symptom crises will be handled after hours.
