Having kept the parts neatly cleansed with tampons of 

 aseptic cotton-wool, and taken up the vessels wherever 

 necessary with artery forceps, the tumour should be care- 

 fully dissected to its base. Here, as a rule, will be found

It must not be forgotten that some tumours, although not 

 malignant, cannot be surgically removed, owing to their 

 large size and the amount of cutaneous and other tissue 

 which would be involved. 



Fig. 47 is an illustration of this, the tumoiTrs (large lipomas) extending 

 almost the entire length of the chest wall.
