What is Lung Cancer?
Lung cancer happens when cells inside the lungs start growing out of control and won't stop. It is the number one cause of cancer deaths in the world. In the Philippines, many people find out they have it late — when symptoms have already become very hard to ignore.
makes up about 85 out of every 100 lung cancer cases. It includes three subtypes: Adenocarcinoma (often found in people who don't smoke), Squamous Cell Carcinoma, and Large Cell Carcinoma
makes up about 15 out of every 100 cases. It grows very fast and is strongly linked to smoking.

Causes and Risk Factors
Cigarette smoke is the main cause — it is responsible for more than 85 out of every 100 lung cancer cases. Radon gas is a natural radioactive gas that comes from the ground and is the second biggest cause. Breathing in someone else's cigarette smoke also raises the risk for people who don't smoke.
Breathing in chemicals like asbestos, arsenic, chromium, nickel, and air pollution over a long period of time can also cause lung cancer. If a family member has had lung cancer, or if a person has had radiation therapy to the chest before, their risk is higher.
Common Symptoms
- A cough that keeps coming back or gets worse over time
- Coughing up blood or spit that looks rust-colored
- Chest pain that often gets worse when breathing deeply or coughing
- Unexplained weight loss and loss of appetite
- Shortness of breath or a wheezing sound when breathing
- Hoarseness or a change in the voice
Diagnosis & Prognosis
Low-Dose CT (LDCT) is the only approved test to screen for lung cancer before symptoms appear. It takes detailed pictures of the lungs using a small amount of X-ray. For people at high risk (ages 50 to 80 who have smoked heavily for many years), doing this test every year can lower the chance of dying from lung cancer by 20 out of every 100 deaths that would have happened without screening.
A CT scan of the chest and upper belly area is the standard first test to see how far the cancer has spread. A PET-CT scan shows which parts of the body have cancer cells that are actively growing — it can look at bones, glands, and the liver. This test helps doctors decide if surgery is possible.
EBUS (Endobronchial Ultrasound) lets doctors take small tissue samples from lymph nodes deep inside the chest without any cuts. This is important for staging — figuring out how far the cancer has spread — and helps doctors choose between surgery or chemotherapy and radiation.
For NSCLC (especially Adenocarcinoma), doctors must test the tumor for specific gene changes. Common ones include EGFR (often found in Asian people who don't smoke), ALK, and ROS1. PD-L1 is another test that tells doctors if a treatment called immunotherapy will work on its own or needs to be combined with chemotherapy.
How well a patient does depends a lot on the stage of the cancer and what gene changes the tumor has. Patients whose cancer has specific gene changes (like EGFR) often do much better with targeted pills than those who don't. Lung cancer found at an early stage can often be cured with surgery or radiation.
Localized (Stage I): About 63 out of 100 people are still alive 5 years later. Regional (Stage II/III): About 35 out of 100. Distant (Stage IV): About 7 out of 100. These numbers come from older data — new treatments like immunotherapy and targeted drugs are helping Stage IV patients live much longer today.
Treatment Options
For early-stage NSCLC, removing the affected lobe of the lung (lobectomy) is the best treatment. Surgeons can now do this through small cuts using VATS (video-assisted surgery) or robotic tools, which means less pain and a faster recovery.
SBRT (Stereotactic Body Radiotherapy) delivers very high doses of radiation aimed exactly at the tumor. It is used when a patient cannot have surgery. For small tumors, it works almost as well as surgery to cure the cancer.
Targeted therapy uses pills that attack specific gene changes in cancer cells. For example, Osimertinib targets EGFR and Alecensa targets ALK. These pills usually have fewer side effects than traditional chemotherapy and can keep cancer under control for years.
Immunotherapy uses drugs that help the body's own immune system find and destroy cancer cells. Pembrolizumab (Keytruda) is one example. In Stage III NSCLC, a drug called Durvalumab given after chemotherapy and radiation is now the standard way to prevent the cancer from coming back.
Jinshazhou Hospital specializes in treating lung cancer using multiple approaches together, including 4D-CT guided radiotherapy, the latest immunotherapy treatments, and targeted therapy based on complete gene testing.

Staging & Symptoms by Stage
Lung cancer stages are measured using the TNM system — T describes the tumor's size, N describes whether lymph nodes are involved, and M describes whether it has spread to other parts of the body. Symptoms change depending on the stage.
The tumor is small and stays only in the lung. Most patients have no symptoms — the cancer is usually found by accident on a scan done for another reason. The chance of being cured is very high (about 70 to 90 out of 100).
The tumor is larger, or cancer cells have spread to lymph nodes near the lung. The patient may have a cough that won't go away or mild chest pain. Surgery is usually the first treatment, followed by chemotherapy.
Cancer has spread to lymph nodes in the middle of the chest. Symptoms include trouble breathing, chest pain, and voice changes. Treatment involves a combination of chemotherapy, radiation, and often immunotherapy.
Cancer has spread to other parts of the body — like the brain, bones, liver, or the other lung. Symptoms can include major weight loss, bone pain, headaches, and feeling very tired. Treatment focuses on slowing the cancer and keeping the patient as comfortable as possible.
What to Do If You Notice Symptoms
Noticing possible symptoms can be frightening — but taking the right steps quickly can dramatically change the outcome. Most symptoms are caused by non-cancerous conditions, but only a doctor can tell for sure.
⚠️ Go to the ER immediately if you experience: severe difficulty breathing, heavy uncontrollable bleeding, sudden severe pain, loss of consciousness, or stroke-like symptoms (facial drooping, one-sided weakness, slurred speech).
Note what you feel, when it started, how often it happens, and what makes it better or worse. List all medications you take and any family history of cancer.
Don't wait for symptoms to go away on their own. Persistent symptoms lasting more than 2–3 weeks always need medical evaluation.
Ask your doctor which tests they are ordering and why. Request a physical copy of every result. If a biopsy is needed, ask about molecular and genetic testing on the tissue sample.
- Don't rush into treatment. Take 1–2 weeks to gather information and a second opinion before committing to a plan.
- Request an MDT review. The best outcomes come from cases reviewed by surgeons, oncologists, radiation specialists, and pathologists together.
- Always get a second opinion. A second opinion is standard practice, not an insult to your doctor.
- Ask about clinical trials. They often give access to treatments not yet widely available locally.
The Cost of Waiting
Most people don't delay treatment out of carelessness. They delay because life is busy, symptoms seem minor, and fear makes it easier to wait. But with lung cancer, every month of delay has a measurable cost — financial, physical, and personal.
A symptom appears — unusual fatigue, a persistent change, something that wasn't there before. It's easy to dismiss. "I'll wait and see if it goes away."
The symptom hasn't resolved. Life is busy. The thought of a diagnosis is frightening. Another month passes.
Pain, weight loss, or visible changes force the issue. A doctor is finally seen. Initial tests begin — but results take weeks, and the referral chain adds more time.
The lung cancer has spread beyond its original site. Surgery alone is no longer sufficient. The plan now involves multiple treatments running together — and the goal shifts from cure to control.
Multiple chemotherapy lines. Targeted therapy. Repeat hospitalizations. Extended leave from work. The financial burden compounds every month treatment continues — with no clear end date.
The Financial Reality
Realistic cost ranges based on standard oncology care pathways in the Philippines and abroad. Actual costs vary by hospital, regimen, and stage.
- Primary treatmentSurgery + adjuvant chemo or radiation
- Duration4–6 months
- Hospitalizations1–2 planned admissions
- Work impact3–6 months leave
- 5-year survival70–90%
- Primary treatmentMultiple chemo lines + targeted therapy
- Duration12–36+ months, ongoing
- HospitalizationsMultiple unplanned admissions
- Work impact12+ months or permanent
- 5-year survival10–30%
💡 Why the gap is so large: Early-stage lung cancer often needs one treatment (surgery). Late-stage needs several running at once — and when one stops working, another line begins. Costs multiply, and they don't stop.
The financial weight of cancer treatment can feel overwhelming — but it rarely has to be borne by one person. The people in your life — family, friends, community — love you, and most of them would do anything to help if they only knew what you were going through. Let them in. Share what you are facing. You may be surprised how quickly people rally when someone they care about needs them. A diagnosis is not a burden to hide — it is an invitation for the people who matter most to show up for you.
Why Patients Choose Jinshazhou Hospital of GZUCM
Most Filipino patients with lung cancer eventually discover that the treatments with the best outcomes — NanoKnife (IRE) for inoperable tumors, CyberKnife SBRT for sub-millimetre precision radiotherapy, proton therapy, CAR-T cell therapy, and comprehensive molecular profiling — are either unavailable in the Philippines or require months-long waiting lists. Jinshazhou Hospital of Guangzhou University of Chinese Medicine offers all of these under one roof, with every case reviewed by a standing multi-disciplinary team before a single treatment is recommended. The cost is typically 50–70% less than Singapore, 60–75% less than Thailand, and up to 90% less than the United States — for the same technologies and international-standard care.

Detection & Treatment Timing — Outcome Matrix
Four possible journeys for a lung cancer patient. Detection timing and treatment timing are independent decisions — and each combination produces a measurably different outcome.
Detection
Cancer caught before it spreads. One curative treatment course, short duration. Most patients return to normal life within 6–12 months.
Detected early but treatment was delayed — fear, denial, or access issues. The cancer advanced despite the early window. Outcomes worsen with every month of delay.
Detection
Found at an advanced stage but treatment started immediately. Multiple modalities required. High cost, prolonged treatment, but prompt action improves the odds.
Cancer found late and treatment further delayed. The highest financial burden combined with the lowest chance of long-term survival. Treatment focuses on control, not cure.
Patients treated at Stage I or II typically complete treatment in months — not years. They keep their hair, their energy, their routines. They return to work. They attend their children's graduations, their grandchildren's birthdays. Treatment becomes a chapter in their life, not the whole story.
Advanced treatment today can extend life by months — sometimes years. That time is not a consolation prize. It is the Sunday lunches, the long conversations, the slow mornings you didn't think you'd have. Every day gained is a day with the people who matter most.
Any of us can be taken without warning. But a diagnosis, as frightening as it is, offers something most people never receive: the chance to be intentional — to choose how you spend your time, to say what you've been meaning to say, to be fully present with the people you love most. That clarity is worth something. Don't let it pass without acting on it.
Cancer does not pause. Every week of delay is a week the disease uses to grow, to spread, to make treatment harder and options fewer. What is treatable today may not be operable in three months. What is curable this year may only be manageable next year. The window exists — but it will not stay open. The single most powerful thing you can do right now is pick up the phone and start the conversation. Everything else follows from that one decision.
