Bronchioloalveolar Lung Carcinoma or BAC is a rare type of Lung Cancer.
More often seen in those who are non-smokers.
This tumor often does not continue into the deeper tissues of the Lungs – therefore is described as “non-invasive“.
Has been given a description of arising from distant bronchioles and/or alevoli.
Since its non-invasive – can be classified as carcinoma in situ.
However, this tumor is quite “malignant” and often leads to death.
Bronchioloalveolar carcinoma can be classified quite similar to a more common cancer called Lung Adenocarcinoma.
1.) Mucinous BAC [20-25% of cases]
2.) Non Mucinous BAC [70-80% of cases]
3.) Mixed Mucinous and Non Mucinous [Very rare]
- Weight Loss
- Shortness of Breath
- Sputum production [Blood and/or Mucus]
- Bronchorrhea – a white mucoid or watery expectoration – has been seen in late disease process
CT are helpful in diagnosis
- Complete removal of lobes of lung may be necessary.
- Even after treatment – recurrence is possible.
Chemotherapy Treatment in Non Mucinous BAC cases.
Mucinous BAC cannot be treated by Chemotherapy in most cases.
Metastasis may occur in local lymph nodes, bone and other areas of the body.
