Is there any test to detect if cancer cells are present in the body or if cancer will happen in future?
Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, the abnormal cells can form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood.
Lung cancer is the most common cause of death due to cancer in both men and women throughout the world. According to the U.S. National Cancer Institute, approximately one out of every 14 men and women in the U.S. is diagnosed with cancer of the lung at some point in their lifetime. Lung cancer is predominantly a disease of the elderly; almost 70% of people diagnosed with lung cancer are over 65 years of age, while less than 3% of lung cancers occur in people under 45 years of age.
What Causes Lung Cancer?
The development of lung cancer is strongly associated with cigarette smoking, approximately 90% of lung cancers are attributable to use of tobacco. Pipe and cigar smoking can also cause lung cancer, but the risk is not as high as with cigarette smoking. Tobacco smoke contains more than 4,000 chemical compounds, many of which are cancer causing (carcinogens). Passive smoking, i.e. the inhalation of tobacco smoke by non-smokers who live or work with smokers, is also an established risk factor for the development of lung cancer.
Genetic susceptibility (i.e. family history) may play a role in the development of lung cancer. Other causes of lung cancer include air pollution (from vehicles, industry, and power generation) and inhalation of asbestos fibres (usually in the workplace).
Lung Cancer Symptoms:
Early symptoms and signs of lung cancer:
There may be no symptoms at the onset of the disease. When present, common symptoms of lung cancer may include:
- Coughing: This includes a persistent cough that doesn't go away or changes to a chronic smoker's cough, such as more coughing or pain.
- Coughing up blood: Coughing up blood or rust-colored sputum (spit or phlegm) should always be discussed with your doctor.
- Breathing Difficulties: Shortness of breath, wheezing or noisy breathing (called stridor) may all be signs of lung cancer.
- Loss of Appetite: Many cancers cause changes in appetite, which may lead to unintended weight loss.
- Fatigue: It is common to feel weak or excessively tired.
- Recurring infections: Recurring infections, like bronchitis or pneumonia, may be one of the signs of lung cancer.
Signs of advanced stages of lung cancer: Advanced stages of lung cancer are often characterized by the spread of cancer to distant sites in the body. This may affect the bones, liver or brain. As other parts of the body are affected, new lung cancer symptoms may develop, including:
- Bone pain
- Swelling of the face, arms or neck
- Headaches, dizziness or limbs that become weak or numb
- Lumps in the neck or collar-bone region
Treatment: Treatment for cancer involves a combination of surgery to remove cancer cells, chemotherapy and radiation therapy to kill cancer cells. Lung cancer is incurable unless complete surgical removal of the tumour cells can be achieved. Surgery is the most effective treatment for lung cancer, but only a few percentage of lung cancers are suitable for surgery i.e. Stage I and II NSCLC and cancer that has not spread beyond the lung.
Radiation therapy may be used for both NSCLC and SCLC and is a good option for people who are not suitable for surgery or who refuse surgery. Chemotherapy is used for both NSCLC and SCLC. Chemotherapy drugs may be given alone or in combination with surgery or radiation therapy. Chemotherapy is the treatment of first choice for SCLC since it has usually spread extensively in the body by the time it has been diagnosed.
Also used in the treatment of lung cancer are targeted therapies. These are drugs (gefitinib and erlotinib) or antibodies (cetuximab, bevacizumab) that block the growth and spread of cancer by interfering with specific molecules involved in tumor growth and progression. They are used in some patients with NSCLC that does not respond to standard chemotherapy.
Hii. Mother had breast cancer n she went through a surgery n chemotherapy in aiims n now there is 3 month delay in radio so is there any harm if radio is getting delay. please answer me.
Brain cancer is a disease of the brain in which cancer cells (malignant cells) arise in the brain tissue. Cancer cells grow to form a mass of cancer tissue (tumor) that interferes with brain functions such as muscle control, sensation, memory, and other normal body functions. Tumors composed of cancer cells are called malignant tumors, and those composed of mainly non-cancerous cells are called benign tumors. Cancer cells that develop from brain tissue are called primary brain tumors while tumors that spread from other body sites to the brain are termed metastatic or secondary brain tumors.
- Brain cancer is actually the abnormal growth and uncontrolled growth of the cancer cells in the brain,that forms a tumor in the brain.Tumours can be either benign or malignant.
- Benign brain tumours are abnormal collections of cells that reproduce slowly and usually remain separate from the surrounding normal brain.
- Malignant tumours reproduce and grow quickly. Their borders are hard to distinguish from the normal brain around them.
There are few early symptoms of brain cancer, but as the tumour grows within the confines of the skull, it causes increased intracranial pressure and exerts pressure on the brain, causing signs to develop.
Brain cancer symptoms and signs are varied and depend on the area of the brain involved, but can include:
- Nausea and Vomiting, which, CANSA reports, may be worse in the morning or after a sudden position change.
- Difficulty walking or clumsiness.
- Vision changes.
- Changes in alertness.
- Behavioural impairment.
Brain cancer occurs when there is an uncontrolled growth of cancer cells in the brain that form a malignant brain tumor. The underlying cause of primary brain cancer, cancer that begins in the brain, is not known. Secondary brain cancer is caused by a cancer of another organ in the body, such as the breast, prostate, kidney, skin, or bone, that has spread to the brain.
What are the risk factors for brain cancer?
- Certain inherited conditions, including neurofibromatosis, Von Hippel-Lindau syndrome, Li-Fraumeni syndrome, and Turcot syndrome
- Personal history of cancer or family history of brain cancer
- Impaired immune system
- Radiation therapy of the head
Surgery is the main form of treatment for brain tumors that lie within the membranes covering the brain or in parts of the brain that can be removed without damaging critical neurological functions. The goal is to remove the entire tumor, whenever possible, as a tumor may recur if any tumor cells are left behind. Radiation therapy and chemotherapy are generally used as secondary treatment for tumors that cannot be cured through surgery alone.
Stereotactic radiosurgery is a treatment option that delivers a high concentration of radiation directly to the tumor in order to stop its growth, while delivering only a minimal dose of radiation to the surrounding tissue. Unlike conventional surgery, stereotactic radiosurgery does not require making an incision to remove the tumor. It can be especially effective in patients with many small metastatic brain tumors.

I am suffering with breast pain I think it is swollen also n I have lumps in breast. Can I know the symptoms of breast cancer? Are this symptoms of cancer.
What is cancer. Symptoms of cancer. How can it be treated. Why it is so dangerous disease. How can we prevent this disease.
I am suffering from osmf Oral submucous fibrosis because I was taking gutkha and occasional cigarettes for 8 years now I left everything for good from 4th July 2015. But I get blood in my saliva sometimes if I talk too much for the whole day in my school and private tuitions I am taking colostrum capsules with dentist recommendation. My mouth opening is improving. Before I found it hard to even put my toothbrush. But now I can eat most other food stuff .however I also feel numbness in my throat and was having difficulty BREATHING last week. It's gone again. I follow strict oral regime. Take garlic and green tea in morning daily. Eats lots of veggies and fruits. Do I have a chance of oral cancer and what is the problem with me. I always feel gas is formed in my stomach. Thanks.
Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. The abnormal cells are termed cancer cells, malignant cells, or tumor cells. Untreated cancers can cause serious illness and death. Many cancers and the abnormal cells that compose the cancer tissue are further identified by the name of the tissue that the abnormal cells originated from (for example, breast cancer, lung cancer, colon cancer).
Cells become cancer cells because of DNA (deoxyribonucleic acid) damage. DNA is in every cell and it directs all the cell’s actions. In a normal cell, when DNA gets damaged the cell either repairs the damage or the cell dies. In cancer cells, the damaged DNA is not repaired, and the cell doesn’t die like it should. Instead, the cell goes on making new cells that the body doesn’t need. These new cells all have the same abnormal DNA as the first cell does.
Cancer has largely remained incurable due to its complexity and its ability to spread rapidly and uncontrollably. There are over 200 types of cancers; most can fit into the following categories
- Carcinoma: Cancer that begins in the skin or in tissues that line or cover internal organs
- Sarcoma: Cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue
- Leukemia: Cancer that starts in blood-forming tissue such as the bone marrow and causes large numbers of abnormal blood cells to be produced and enter the blood
- Lymphoma and myeloma: Cancers that begin in the cells of the immune system
- Central nervous system cancers: Cancers that begin in the tissues of the brain and spinal cord Tumors can be benign or malignant.
- Benign tumors aren’t cancerous: They can often be removed, and, in most cases, they do not come back. Cells in benign tumors do not spread to other parts of the body.
- Malignant tumors are cancerous: Cells in these tumors can invade nearby tissues and spread to other parts of the body. The spread of cancer from one part of the body to another is called metastasis.
Cancer symptoms are vary in different people and depend on where the cancer is located, where it has spread, and how big the tumor is. Some cancers can be felt or seen through the skin – a lump on the breast or testicle can be an indicator of cancer in those locations. Skin cancer (melanoma) is often noted by a change in a wart or mole on the skin. Some oral cancers present white patches inside the mouth or white spots on the tongue.
Other cancers have symptoms that are less physically apparent. Some brain tumors tend to present symptoms early in the disease as they affect important cognitive functions. Pancreas cancers are usually too small to cause symptoms until they cause pain by pushing against nearby nerves or interfere with liver function to cause a yellowing of the skin and eyes called jaundice. Symptoms also can be created as a tumor grows and pushes against organs and blood vessels. For example, colon cancers lead to symptoms such as constipation, diarrhea, and changes in stool size. Bladder or prostate cancers cause changes in bladder function such as more frequent or infrequent urination.
As cancer cells use the body’s energy and interfere with normal hormone function, it is possible to present symptoms such as fever, fatigue, excessive sweating, anemia, and unexplained weight loss. However, these symptoms are common in several other maladies as well. For example, coughing and hoarseness can point to lung or throat cancer as well as several other conditions.
When cancer spreads, or metastasizes, additional symptoms can present themselves in the newly affected area. Swollen or enlarged lymph nodes are common and likely to be present early. If cancer spreads to the brain, patients may experience vertigo, headaches, or seizures. Spreading to the lungs may cause coughing and shortness of breath. In addition, the liver may become enlarged and cause jaundice and bones can become painful, brittle, and break easily. Symptoms of metastasis ultimately depend on the location to which the cancer has spread.
Cancer arises from one single cell. The transformation from a normal cell into a tumour cell is a multistage process, typically a progression from a pre-cancerous lesion to malignant tumours. These changes are the result of the interaction between a person’s genetic factors and three categories of external agents, including:
- Physical carcinogens – such as ultraviolet and ionizing radiation;
- Chemical carcinogens – such as asbestos, components of tobacco smoke, aflatoxin (a food contaminant) and arsenic (a drinking water contaminant); and
- Biological carcinogens – such as infections from certain viruses, bacteria or parasites.
Ageing is another fundamental factor for the development of cancer. The incidence of cancer rises dramatically with age, most likely due to a buildup of risks for specific cancers that increase with age. The overall risk accumulation is combined with the tendency for cellular repair mechanisms to be less effective as a person grows older.
It is important to point out that most everyone is exposed to cancer-causing substances (for example, sunlight, cigarette smoke, and X-rays) during their lifetime but many individuals do not develop cancer. In addition, many people have the genes that are linked to cancer but do not develop it. Higher the amount or level of cancer-causing materials a person is exposed to, the higher the chance the person will develop cancer. In addition, the people with genetic links to cancer may not develop it for similar reasons (lack of enough stimulus to make the genes function). In addition, some people may have a heightened immune response that controls or eliminates cells that are or potentially may become cancer cells. There is evidence that even certain dietary lifestyles may play a significant role in conjunction with the immune system to allow or prevent cancer cell survival. For these reasons, it is difficult to assign a specific cause of cancer to many individuals.
Ayurveda, one of the major traditional forms of medical practice in India, has produced many useful leads in developing medications for chronic diseases. Ayurveda is an intricate system of healing that originated in India thousands of years ago. Historical evidence of Ayurveda can be found in the ancient books of wisdom known as the Vedas that were written over 6000 years ago. Ayurveda provides novel approaches to cancer prevention that are considered safe. Classical Ayurvedic texts have several references to cancer. Some terms used to describe the condition are general while others are much more specific.
Arbuda is the most specific term for a cancerous malignancy. Gulma is one another reference used to describe any palpable hard mass in the abdomen. It is any hard, tumor like mass in the abdominal region, which could be benign or malignant. Ayurvedic classification of neoplasms depends upon various clinical symptoms in relation to tridoshas.
- Group I: Diseases that can be named as clear malignancies, including arbuda and granthi, such as mamsarbuda (sarcomas) and raktarbuda (leukaemia), mukharbuda (oral cancer), and asadhya vrana (incurable or malignant ulcers).
- Group II: Diseases that can be considered as cancer or probable malignancies, such as ulcers and growths. Examples of these are mamsaja oshtharoga (growth of lips), asadhya galganda (incurable thyroid tumour), tridosaja gulmas, asadhya udara roga, (abdominal tumours like carcinomas of the stomach and liver or lymphomas).
- Group III: Diseases with the possibility of malignancy, such as visarpa (erysipelas), asadhya kamala (incurable jaundice), asadhya pradara (intractable dysmenorrhea or leukorrhea) and tridosaja nadi vrana (intractable sinusitis).
Effective treatment for cancer, focusing on the principle of detoxification, rejuvenation. Our treatment involves:
- Shamana chikitsa (treatment using Ayurvedic medicines orally)
- Shodhana chikitsa (detoxification through Panchakarma therapy)
- Rasayana chikitsa (immunotherapy, rejuvenation or Kayakalpa)
- Diet & life style management
- Satvavajaya (couselling)
- Daiva vyapashraya chikitsa (divine therapy), Yoga & Pranayama are also suggested as per the need and condition of the patient.
- Our cancer therapies are based on the philosophy of Removal the cancerous cells when possible and destroy any cells that remain.
Our Ayurvedic treatments can be safely combined with chemotherapy and radiotherapy procedures to minimize the side effects. Even in surgical treatment, this treatment can be started immediately to prevent metastasis and further healing.
