The term refers to the spread of malignant cells through blood and lymph to one side of the body is termed Chemicals that cause damage during embryonic or fetal development are called distant sites all over the body. 8. What are examples of at least 5 warning signs of possible cancers? Give the warning sign and type of cancer (there may be more than one warning sign associated witha particular type of cancer) What are 2 of the risks to the developing human from smoking during pregnancy, 2 risks from the excessive consumption of alcohol and 2 risks from too many CAT scans during pregnancy?

Answer 1

1. Sarcoma is the malignant cancer that arise from the connective tissue.

2. Lipomas is the benign cancer that arise from the adipose tissue.

3. Genetic engineering involves the modifying or changing DNA sequence.

4. USG in pregnancy can helps to detect the organ development. Mainly brain and heart abnormalities are detected.

5. Paralysis occurs as symmetrical in any area of body is Diplegia whereas paralysis in one side of body is hemiplegia.

6. Chemicals cause damage to the fetus are called as Teratogens.

7. Spread of malignant cells are termed as Metastasis.

8. Change in bowel or bladder, sore does not heel, Unusal bleeding, Thickening or lump in the body, Indigestion.

Breast cancer: bleeding or discharge from nipple, lump in the breast

Oral cancer: A growth or tumour in the mouth, Development of lump or sore.

Lung cancer: Pain in chest that occurs even during breathing ,haemoptysis.

Laryngeal cancer: Lump or thickness in the neck, hoarseness for long period of time.

Prostate cancer: Pain during urination, blood in urine.

9. Risk due to smoking: It reduce the oxygen supply to the fetus hence can cause miscarriage and stillbirth.

Risk due to alcohol: Passage of alcohol to the growing fetus can result in brain problems, birth defects and premature birth.

Risk due to CAT scan: Radiation in pregnancy affects fetal growth. Growth retardation, malformations and impair the brain function.
