Several types of breast cancer

There are two main groups of lung cancer.

Small cell lung cancers (SCLC), which are closely linked to tobacco use. These account for 15% of all lung cancers.

Non-small cell lung cancers (NSCLC): these account for more than 80% of all lung cancers. They include the following:

  • adenocarcinoma, currently accounting for 60% of cases
  • epidermoid carcinoma, accounting for 30% of cases
  • large cell carcinoma, which are more rare

Treatment of these tumors is very different and must be tailored to suit each patient.
