New Hope for Breast Cancer

Breast Cancer is malignant growth of breast tissue usually within milk ducts. Breast is sensual part of women, that part of their attractiveness, and increase women confidence. But the bad news is breast is the common place for cancer to growth. From the stastisic, breast cancer rank about top incidence cancer in women. And also rank as top leading cause of death in cancer patients.

With the development of current knowledges and researchs by scientists, there is an improvement in health care, diagnostic procedures, treatment options for breast cancer.

Cancer Growth
Cancer is genetic disease, since the main problem is located in cell nuclei. Cell begin to growth out of control, and demand more nutrient compare to other tissues. There are lot of theory explaning cancer growth. Cancer cell is not an instant process eventhough they growth so fast.


Cancer cell usually need a serial of DNA damaged as initiation, beside this they also need a promotor for their growth during early phase. At this phase, cancer cell also difficult to detect, and cause no symptoms. But after serial of replication their gaining more capabilities and behave more aggresively. Thus make cancer grows bigger and invasive to other tissues.

Metastasis as part of cancer characteristics that differentiate it from benign tumor. Metastasis is a capability of cancer cell to migrate and growth at different site from the primary site.

Cancer which has already metastasis, has worse prognosis compare to none. Commonly the patient with metastasis is in terminal stage, and the patient mostly treated palliatively.

New Hope in Breast Cancer
As, I describe above about the cancer growth. Cancer deaths about 90% are due to the spread of breast cancer. Commonly metastasis of the breast cancer cell is located in the lungs.

Hope in Breast Cancer

Nowadays, a breakthrough in knowledge, that the researchers have discovered the switch that enables breast cancer cells to travel to and be received in the lungs.

Metastasis was long thought a late event in cancer progression, but now is have been shown to be an early event that is dependent on HIF-1. HIF-1 itself a protein that controls genes that enable cells to survive in low oxygen, like cells in solid tumors.

In order for breast cancer cells to spread to lungs, they must leave the breast, enter blood vessels that lead to the lungs, and exit those same vessels. Blood vessels are pretty tight, a cell has to work pretty hard to get through the vessel wall. HIF-1 triggers the lung tissue to prepare for arriving breast cancer cells, and it also has role in helping cells to get access to blood vessels for their migration.

Lastly, a few years ago, John Hopkins research team found that digitalis/digoxin, commonly used to treat irregular heartbeats, can block HIF-1 production and can stop liver and prostate cancer cells from growing. And from their research they conclude that digitalis/digoxin could be use in treatment of breast cancer, since it has role in blocking HIF-1 and slow breast cancer growth and metastasis.

Eventhough, the research isn't finished yet. But, the hope that it bring for future, maybe could improve human health. Innovation is needed, we can't keep doing with same methods and hoping the different result.

We can't rely our life on dream or hope without efforts, but the people who has dream are innovative ones.

Rising Health Consent about Fukushima

March 11, 2011, will be the day that japaneses gonna record that in their history just like the day of atomic bomb of hiroshima and nagasaki.
Japan was hit by 8.9 Ritcher scale of earthquake follow by tsunami, what devastating force of nature. One of the big disaster of decade after Aceh's Tsunami, and Haiti Earthquake.

Japan's disaster is more complicated than we though, eventhough the impact of earthquake to building is minimal. The explosion of Fukushima nuclear reactor makes the problems become complicated.
Because, our modern civilization is very traumatic to anything about nuclear radiation. Our history had already faced nuclear radiation two times, first japan atomic bomb, second the Chernobyl accident.

In this article, i won't discuss about the nuclear technology, but about the impact of radiation to our health.
Atomic Bomb

Radiation
Radiation is energy in the process of being transmitted, which may take such forms as light, or tiny particles much too small to see. Visible light, the ultra-violet light we receive from the sun and from sun-beds, and transmission signals for TV and radio communications are all forms of radiation that are common in our daily lives. These are all referred to as 'non-ionizing' radiation.

Radiation particularly associated with nuclear medicine and the use of nuclear energy, along with X-rays, is 'ionizing' radiation, which means that the radiation has sufficient energy to interact with matter, especially the human body, and produce ions, i.e. it can eject an electron from an atom.

X-rays from a high-voltage discharge were discovered in 1895, and radioactivity from the decay of particular isotopes was discovered in 1896. Many scientists then undertook study of these, and especially their medical applications. This led to the identification of different kinds of radiation from the decay of atomic nuclei, and understanding of the nature of the atom. Neutrons were identified in 1932, and in 1939 atomic fission was discovered by irradiating uranium with neutrons, and this led on to harnessing the energy released by fission.

In order to quantify how much radiation we are exposed to in our daily lives and assess potential health impacts as a result, it is necessary to establish a unit of measurement. The basic unit of radiation dose absorbed in tissue is the gray (Gy), where one gray represents the deposition of one joule of energy per kilogram of tissue.

However, since neutrons and alpha particles cause more damage per gray than gamma or beta radiation, another unit, the sievert (Sv) is used in setting radiological protection standards. This unit of measurement takes into account biological effects of different types of radiation. One gray of beta or gamma radiation has one sievert of biological effect, one gray of alpha particles has 20 Sv effect and one gray of neutrons is equivalent to around 10 Sv (depending on their energy). Since the sievert is a relatively large value, dose to humans is normally measured in millisieverts (mSv), one-thousandth of a sievert.

Limiting exposure
Public dose limits for exposure from uranium mining or nuclear plants are usually set at 1 mSv/yr above background.

In most countries the current maximum permissible dose to radiation workers is 20 mSv per year averaged over five years, with a maximum of 50 mSv in any one year. This is over and above background exposure, and excludes medical exposure. The value originates from the International Commission on Radiological Protection (ICRP), and is coupled with the requirement to keep exposure as low as reasonably achievable (ALARA) – taking into account social and economic factors.

Radiation protection at uranium mining operations and in the rest of the nuclear fuel cycle is tightly regulated, and levels of exposure are monitored.

There are four ways in which people are protected from identified radiation sources:
Limiting time. In occupational situations, dose is reduced by limiting exposure time.
Distance. The intensity of radiation decreases with distance from its source.
Shielding. Barriers of lead, concrete or water give good protection from high levels of penetrating radiation such as gamma rays. Intensely radioactive materials are therefore often stored or handled under water, or by remote control in rooms constructed of thick concrete or lined with lead.
Containment. Highly radioactive materials are confined and kept out of the workplace and environment. Nuclear reactors operate within closed systems with multiple barriers which keep the radioactive materials contained.

Effects of radiation
Our knowledge of radiation effects derives primarily from groups of people who have received high doses. The risk associated with large radiation doses is relatively well established. However, the risks associated with doses under about 200 mSv are less obvious because of the large underlying incidence of cancer caused by other factors. Radiation protection standards assume that any dose of radiation, no matter how small, involves a possible risk to human health. However, available scientific evidence does not indicate any cancer risk or immediate effects at doses below 100 mSv a year. At low levels of exposure, the body's natural repair mechanisms seem to be adequate to repair radiation damage to cells soon after it occurs.

Radiation effects to our health, depend on the time of exposure, dose/intensity of radiation, our body repair mechanism. Ionizing radiation interact with our body and causing health effects. Radiation also bring thermal energy thus effect will gives short-term effects especially at high dose.

Person that achieving high dose of radiation, will experienced thermal injury at short term that may cause death. Besides that high dose of radiation will cause serious cell death, that will give serious complication such gastrointestinal bleeding, and internal bleeding, and less potential to be rescue.

Mostly person experienced a radiation at low dose, thus will experienced any health effects at short-term, but will experience complication later on, at long-term.
Radiation and health effects

Ionizing radiation will damage the cell, but the most crucial damage is in the DNA, once DNA is damaged, our body will undergo repair mechanism or self-destroy. But, some cell with unrepaired DNA damaged, that mutation of genetic materials will bring serious consequences later, such as cancer and bone marrow suppresion. This health effects is very difficult to predict since we can't place an accurate threshold of radiation. Besides the cancer, genetic mutation, also lead to congenital anomalies later on.

Nuclear Radiation is very harmful technology, but if we can use it wisely, it can give us a benefits, since the amount of the energy that come out from nuclear is far exceed other source of energy

"Pray for Japan"
I hope Japan's Government can solve the problems, and Japan can rise again like the sun.

Good Cholesterol Lowers Colon Cancer Risk

On March 2011, Scientists published their study about relationship between colon cancer and blood cholesterol ---- Higher concentrations of serum high-density lipoprotein (HDL) cholesterol are associated with a reduced risk of colon cancer, according to a study published online in Gut.

Colon cancer is one most common cancer, and also one of leading cause of death by cancer. Colorectal cancer is a major health burden worldwide. The overall incidence and mortality from colon cancer has been on a slow decline over the past 20 years in the United States; however, colon cancer remained the third most common cause of cancer-related mortality in 2008. A multitude of risk factors have been linked to colorectal cancer, including heredity, environmental exposures, and inflammatory syndromes affecting gastrointestinal tract.
Colon Cancer

Brief about Colon Cancer
Cancer is abnormal growth of tissue that invades and destroy the adjacent tissues. Colon cancer one the most common cancer, it occurs in the epithelial tissues of large bowel. Cancer is a challenging topic for medicine field since its complexity and difficulties.
Mostly cancer can be treated successfully if the cancer is in early stage, this is also happens in colon cancer, thats way people about 50 years age is recommended to do routine colon in loop in order to screen any lesion that can develop into cancer.

Besides the screening, indentifying and avoiding risk factors also increasing protective factors may help prevent cancer.

Avoiding cancer risk factors such as smoking, being overweight, and lack of exercise may help prevent certain cancers. Increasing protective factors such as quitting smoking, eating a healthy diet, and exercising may also help prevent some cancers.

Risk factors of Colon Cancer
- Age
The risk of colorectal cancer begins to increase after age 40 and continues to increase as you get older.

- Obesity and lack of exercise
Obesity is linked to an increased risk of colorectal cancer. A lifestyle that does not include regular exercise may also be linked to an increased risk of colorectal cancer.

-Smoking
Smoking cigarettes is linked to an increased risk of developing colorectal adenomas (noncancerous tumors) and colorectal cancer. Cigarette smokers who have had surgery to remove colorectal adenomas have an increased risk for the adenomas to recur (come back).

- Alcohol
Drinking alcoholic beverages may increase the risk of colorectal cancer.

- Diet
It is not known if a diet low in fat and high in fiber, fruits, and vegetables lowers the risk of colorectal cancer.
Some studies have shown that a diet high in fat, proteins, calories, and meat increases the risk of colorectal cancer, but other studies have not.

Cholesterol and Colon Cancer
Colon cancer researchs about prevention and early detection are quite a lot of, since it is important to identify the risk factors to promote the prevention thus lowers the incidence of cancer.

Recently, there is a new publication about relationship between HDL and Colon Cancer. The trial showed that the higher HDL level is associated with lower risk of having colon cancer.

HDL is well known worldwide as the protective factors for cardiovascular disease, and now is associated with lower risk of colon cancer.

The possible explanation, actually there is no proven theory/explanation from the scientists yet. But i would try to answer it.

From the trial, it is said HDL relationship with colon cancer was independent from other markers of vascular disease such as insulin resistance, and inflammation.

I think the higher HDL level in patient is associated with the patient lifestyle and habits. Mostly higher HDL level are found in patients with healthy diet (low consumption of fat and cholesterol, high fiber) also patients that physically active, and maybe nonsmokers.

From that, we can see that actually the way to increase the HDL level, just the same with the way to avoid the risk factors of colon cancer. So it means the study isn't important?
No, i think this study gives us, something important eventhough it will need further research about it.
Good Cholesterol

My recommendation or conclusion, we can use HDL as objective markers of our prevention efforts to avoid colon cancer risk factors. Since we can't measure how healthy someone's lifestyle based on person speech. With the measurement of HDL, we can get objective result about someone healthy lifestyle.

At the end, my message is Keep Healthy

Non-smoking Has Different Type of Lung Cancer

Introduction
Cancer is disease that characterized by uncontrolled growth of cell grow and multiplication, and malfunction. Cancer is malignant, because its invasive behaviour. Cancer tissues are dangerous for host because they take oxygen, nutrients, and space from healthy cells and they invade and destroy or reduce the ability of normal tissues to function.
