Two Main Types — and Why It Matters
Two Main Types — and Why It Matters
When doctors talk about lung cancer, they’re usually referring to one of two main types: non-small cell lung cancer (NSCLC) or small cell lung cancer (SCLC).
1
NSCLC is the most common form, making up about 85% of all cases. It tends to grow and spread more slowly, which often gives patients more treatment options—such as surgery, targeted therapy, or immunotherapy—depending on the stage and overall health.
2
SCLC, on the other hand, is less common but usually more aggressive. It can spread quickly, and treatment often begins right away with chemotherapy or radiation to help control its growth.
Understanding which type you have is more than just a medical detail—it guides every decision that follows. Your diagnosis helps your care team decide the best next steps, from treatment planning to supportive care, ensuring you get the approach that fits your unique situation.
What ‘Stage’ Really Means
What ‘Stage’ Really Means
When doctors talk about the stage of lung cancer, they’re describing how far the cancer has grown or spread. Staging helps your care team plan treatment and understand what comes next.
Stage I
The cancer is small and still contained within the lung.
Stage II
It has grown slightly or may have reached nearby lymph nodes.
Stage III
The cancer has spread to more lymph nodes or tissues near the lungs.
Stage IV
The cancer has spread (metastasized) to other parts of the body, such as the bones or liver.
Your stage doesn’t define your future—it simply helps guide your care. Your doctor will explain what your stage means for treatment and next steps, making sure you understand every part of the plan ahead.
Go Into Appointments Prepared
Go Into Appointments Prepared
When you’re facing a new diagnosis, every appointment can feel like information overload. Going in prepared helps you stay focused and confident.
Bring a printed list of questions so you don’t forget what matters most to you—whether it’s about treatment options, side effects, or daily life during care. Writing down your symptoms, side effects, and emotional concerns between visits also gives your care team a clearer picture of how you’re doing.
And don’t go it alone. Bringing a friend or family member can make a big difference—they can help take notes, ask questions you might miss, and offer support when things feel overwhelming.
Being organized and proactive helps you get the most out of every conversation with your medical team.
