Get to Know what is cancer

All over the world, cancer is known to be as one of the most deadly disease ever to have affected the human race. Most of the medical researchers all over the world, consider cancer to be a “metabolic disease”. Metabolic diseases are those diseases, which are known to affect the metabolism rate of the human body. As already said, we know that cancer has been concluded as to be a “metabolic disease” and that conclusion has been drawn from the fact that, cancer as a disease affects the human cells in the body.

Cells are microscopic living units in the body, which together form all living organs in the body. At any given time or state, the human body is made up of a billion cells, which together constitute the human organs. Cancer as a disease is considered to be a very deadly disease, just because of the fact that the disease affects the human cells. In cancer, abnormal and unusual cells crop up in the human body and they grow and spread in the human body at an alarming and fast rate. The abnormal cells grow and star spreading at a very fast rate. Usually, the normal cells divide and grow up to a certain level and then they die after a little time, unlike the unusual cells which do not follow the normal rate of growth and division. The cancer cells keep on dividing and continue growing on unlike the usual cells. The cancer cells unlike the usual cells do not die and start getting clumped together, which in turn forms a tumor.

It is said that cancer actually is a stage in the body when the cells turn, “trophoblastic”. Trophoblastic is a situation in the human body, when the cells in the human body tend to multiply at a faster rate than the normal. This stage can be explained for example, when a human body gets an external or internal injury, then the cells of the human body start the healing process, by starting to multiply.  In case, the cells are in a trophoblastic stage, then although the cells start healing, but they don’t stop multiplying, thereby causing a lump. This in medical term is also called as a tumor. This lump goes numb even if the body controls the growth of the trophoblastic cells and proves to be highly injurious if the cells keep spreading. The removal of such tumor would rather lead to the uncontrolled growth of those trophoblastic cells, because of more effected sited due to the operation, and thus result in increasing the cancer.

The known medical treatments for cancer are radiation therapy and chemotherapy. But neither radiation therapy is effective due to the reason it creates more wounded parts and thus increases the cancer cells, nor chemotherapy is effective because it adversely effects the immune system of the body and the body holds no-more ability of natural healing.

Prostate Cancer

Introduction:-

Prostate is a glandular organ present only in males.  It surrounds the neck of bladder & the first part of urethra and condributes a secretion to the semen. The gland is conical in shape and measures 3 cm in vertical diameter and 4 cm in transverse diameter.It has got five lobes anterior,posterior,two lateral and a median lobe.Since  the first part of the urethra pass through it any lesion in the prostate will produce difficulty in passing urine.

Diseases of the prostate gland:-

1) Prostatitis:-

This is the inflamation of the prostate gland due to bacterial infection.

2) Benign enlargement of the prostate:-

This is a non cancerous tumour of  the prostate seen after the age of 50.  3,Cancer of the prostate:-This is the 4th most common cause of death from malignant diseases in males.

Cancer of the prostate.

Cancer of the prostate is directly linked with the male sex hormones(androgens).If the levels of sex hormone increases the growth rate of cancer also increases.It is found that after the removel of testes there is marked reduction in the size of tumour.

Site of tumour:-

Prostate cancer is seen mainly in the posterior lobe.Non cancerous enlargement is seen in other lobes.

Changes in the gland in cancer:-

The gland becomes hard with irregular surface with loss of normal lobulation .Histologically prostate cancer is an adeno carcinoma(cancer of the epithelial cells in the gland)

Growth :-

Growth rate is very fast in prostate cancer .The tumour compresses the urethra and produce difficulty in urination.

Spread of tumour:-

Metastasis in cancer of prostate is very early.

1) Local spread:-

From the posterior lobe the cancer cells go to the lateral lobes and seminal vesicles.Tumour cells also move to the neck and base of the urinary bladder.

2) Lymphatic spread:-

Through the lymph vessels cancer cells reach the internal and external illiac group of lymph nodes.From there cells move to retroperitonial(Behind the peritonium) and mediastinal lymph nodes(in the chest)

3) Spread through the blood:-

Spread of cancer cells takeplace through the periprostatic venous plexus and reaches the vertebral veins while coughing and sneezing and finally enders the vertebral bodies of the lumbar vertebrae.

Signs and symptoms of prostate cancer:–

Signs and symptoms depend upon the stage of the cancer. The following symptoms may be seen.

1) No symptoms:-

Tumour is small and only in the posterior lobe.  This is diagnosed accidentely.

2) Slight difficulty in urination:-

Here the tumour is enlarged and urethra is slightly compressed.Shortly there will be frequent urge for urination with difficult urination.

3) When the tumour spread to all nearby areas including neck of bladder and urethra there will be painful urination with bleeding.Urine comes drop by drop.

4) Retention of urine:-

When the urethra is completely compressed there will be retention of urine.This can lead to hydronephrosis, renal failure ect.In this condition patient may get convulsions due to renal failure and finally coma.

5) Signs of metastasis:-

Some patients come with the signs and symptoms of metastasis.

a) Lumbo sacral pain due to spread of cancer cells to lumbar and sacral vertebrae.

b) Fracture of spine due to cancerous growth in the spine.

c) Swelling, pain and fluid collection in the abdomen due to lesion in the abdomen.

d) Respiratory complaints due to cancer of mediastinal lymphnodes and lungs.

e) General weakness due to spread of cancer to different parts of the body.

f) Anaemia due to involment of bone marrow and increased destruction of RBCs.

Clinical examination :-

Includes per rectal examination to feel the prostate gland,palpation of abdomen to feel the swelling in kidneys and any tumours.Patient is examined from head to foot to find out any lesions.

Investigations:-

1) Complete blood investigations;-

RBC,WBC,Platlets,ESR,bleeding time ,clotting time ect.

2) Urine analysis:-

Microscopic examination to detect pus cells,occult blood,casts,Crystals ect.

3) Renal function tests:-

Blood urea level,serum creatinine level,electrolyte level ect.

4) Serum acid phosphatase:-

Increased in cancer of prostate.

5) x-ray of the spine:-

To detect any tumour or fracture.

6) Ultra sonography;-

Gives idea about prostate,bladder,kidney ect.

7) C T scan:-

More detailed information about organs and tumour.

8) MRI of the spine:-

Gives detailed information about spine ,disc and nearby soft tissues.

9) Lymphangiography:-

Gives idea about lymphatic spread of cancer.

10) Biopsy to confirm cancer:-

Biopsy is taken from the tumour and is send for histopathological examination under the microscope.This will detect the presence of cancer cells.

Treatment:-

1) If there is retention of urine catheterisation is needed.
2) Dialysis if kidney failure.
3) If there is coma monitoring of all vital functions along with parentral nutrition and electolyte supply.
4) Specific treatment is prostatectomy(removal of prostate)

Partial prostatectomy :-

Here only the affected lobe is removed.

Radical prostatectomy :-

Total removal of prostate along with nearby lymphnodes.

5, Hormone therapy :-

Stilbestrol is given to reduce tumour growth.Since this treatement increases the chance for cardiovascular disease phosphorylated diethyle stilbesterol is used nowadays.

6) Chemotherapy:-Drugs like cyclophosphamide, cisoplatim ect are given.

7) Radiotherapy is also done for some cases.

8) Homoeopathy:-

Homoeopathic drugs like carcinocin, conium, sabal, crotalus, thuja, iodum, selinium, staphysagria, sulphur ect can be given according to symptoms.Constitutional homoeopathic medicine will give great relief and can increase the life span.

9) Yoga and meditation is also healpful.
