BREAST CANCER
SYMPTOMS
•Lump in breast.
•Bloody discharge from nipple.
•Changes in shape or texture of the nipple or breast, peaud’orange
•.
•Skin : Ulcers or redness
•Also common : Cancer related fatigue, swollen lymph nodes or weight
loss
SYMPTOMS
•COUGH(most common early symptom) -mostly dry but
sputum may be purulent if secondary infection occurs.
A change in the character of the ‘regular’ cough of smoker associated with
other new respiratory symptoms.
•HEMOPTYSISespecially tumor arising in central bronchi.
Central tumor invade large vessels, cause massive hemoptysis (fatal).
Repeated episodes of scanty hemoptysis or blood streaking sputum in
smokers.
LUNG CANCER
•BRONCHIAL OBSTRUCTION can lead to pneumonia. Reccurrant
pneumonia at same site or slow response to treatmentin smoker.
Lung abscess may develop.
Signs of displacement of mediastinum or elevation of diaphragm if major
portion of lung collapsed.
•BREATHLESSNESS -occlusion of large bronchus resulting collapse of a
lobe or lung or a large pleural effusion.
•STRIDOR (harsh inspiratory noise) -lower trachea, carina or main
bronchi are narrowed by primary tumor or by compression from malignant
enlargement of the sub cranial & paratracheallymph nodes
•PLEURAL PAIN -Malignant invasion of pleura or distal infection.
Intercostal nerve involvement -pain in chest along nerve root distribution.
•Bronchial Cain apex of lung cause
1. Horner’s syndrome-ipsilateralpartial ptosis, enophthalmos, a small pupil
& hypohidrosisof face.
