Is Stage 3A Lung Cancer Considered as the Middle Stage?

Stage 3A lung cancer is generally not considered mid-stage. Typically, lung cancer is classified into four stages: I, II, III, and IV, based on the TNM staging system.

Stage I:

If the tumor is 3 centimeters or smaller and there is no lymph node metastasis, it is considered early-stage lung cancer. At this stage, patients can undergo surgical treatment such as lung segmentectomy, which can be complemented by radiotherapy and chemotherapy.

Stage II:

If the tumor is larger than 3 centimeters but has not metastasized to distant organs, it is classified as stage II lung cancer. Surgical treatment is also an option for patients at this stage, followed by adjuvant radiotherapy and chemotherapy.

Stage III:

When the tumor has metastasized to lymph nodes, it is classified as stage III lung cancer. Patients at this stage require targeted therapy with medications like gefitinib and erlotinib under medical supervision. If necessary, radiotherapy and chemotherapy may be combined as well.

Stage IV:

If cancer cells have metastasized to distant organs, it is considered late-stage (stage IV) lung cancer. Patients can actively cooperate with doctors for palliative surgeries, stent implantation, and other treatments to help extend their survival. It is recommended that patients seek medical attention promptly, undergo relevant examinations under medical guidance, and receive targeted treatment after a clear diagnosis. Daily diet should be light, avoiding spicy and stimulating foods to prevent aggravation of the condition.
