2. Lung cancer is a disease of uncontrolled cell growth in
tissues of the lung. This growth may lead to metastasis,
which is the invasion of adjacent tissue and infiltration
beyond the lungs. The vast majority of primary lung
cancers are carcinomas of the lung
The main types of lung cancer are small cell lung
carcinoma and non-small cell lung carcinoma.
lung cancer may be seen on chest radiograph and
computed tomography (CT scan). The diagnosis is
confirmed with a biopsy.
3. Symptoms that suggest lung cancer include:
• dyspnea (shortness of breath)
• hemoptysis (coughing up blood)
• chronic coughing pattern
• Wheezing
• chest pain or pain in the abdomen
• cachexia (weight loss), fatigue, and loss of appetite
• dysphonia (hoarse voice)
• clubbing of the fingernails (uncommon)
• dysphagia (difficulty swallowing).
4. •The main causes of lung cancer (and cancer in general)
include:
•carcinogens (such as those in tobacco smoke(
•ionizing radiation
•viral infection.
•Smoking, particularly of cigarettes, is by far the main contributor to
lung cancer.
•nicotine appears to depress the immune response to malignant
growths in exposed tissue.
•The length of time a person smokes increases the person's chance of
developing lung cancer.
•If a person stops smoking, this chance steadily decreases as damage
to the lungs is repaired and contaminant particles are gradually
removed.
5. 1) Sudden Infant Death Syndrome:
2) Stillbirth:
Women who smoke during pregnancy increase the chances of the
death of their babies during pregnancy itself.
3) Low birth weight of the baby:
• Birth weight of the baby is an important factor for the future health of the baby.
• Low birth weight can lead to a great many complications.
• low birth weight is the main reason for pre-natal death (during the first month
after the birth).
6. 5) Respiratory Infections:
the baby is more likely to have asthma and other
respiratory diseases
6) Placenta Abruption:
This condition arises when the placenta pulls the walls
of the uterus either before or during labor.
This requires an immediate delivery usually through
cesarean operation.
A smoker's placenta is thinner making her more likely
to have placenta abruption.
7) Premature birth
