A set of illnesses collectively known as cancer is defined by the uncontrolled division and proliferation of aberrant cells. The process of metastasis, in which these cells infect nearby tissues and spread to different areas of the body, can occur if left unchecked. Although there are over 100 different forms of cancer, each with its own special traits, the most prevalent kinds are covered in the sections that follow.
1. Breast Cancer
Symptoms:
An enlargement in the breastA change in the breast's dimensions, form, or appearance
Secretion from the breasts (other than breast milk)
Dimpling and other changes to the breast's skin
Causes:
Mutations in the genes (BRCA1, BRCA2, etc.)Breast cancer in the family history
Hormonal factors (such as late menopause or early menstruation)
Lifestyle variables (such as obesity and alcohol use)
Treatments:
Surgery (mastectomy or lumpectomy)Radiation treatment
Chemotherapy
Hormone treatment (tamoxifen, for example)
Targeted treatment, such as HER2 inhibitors
2. Lung Cancer
Symptoms:
Chronic cough that gets worse with timeChest ache
Breathlessness
Unexpected weight reduction

Skin cancer in the family history
Exposure to certain substances, such as arsenic
Treatments:
Surgically excising the afflicted regionRadiation treatment

Sun prevention and routine skin examinations
6. Leukemia
Symptoms:

Some blood conditions (like myelodysplastic syndrome)
Treatments:
ChemotherapyRadiation treatment
Transplantation of stem cells
Targeted treatment (tyrosine kinase inhibitors, for example)
Immunotherapy
7. Pancreatic Cancer
Symptoms:
Back discomfort originating in the abdomenJaundice, or the yellowing of the eyes and skin

Palliative care for the treatment of symptoms
8. Ovarian Cancer
Symptoms:
Abdominal bloating or swellingPain in the abdomen or pelvis
Having trouble eating or getting satisfied quickly
Urinating frequently or urgently
Weight loss
Causes:
